On fixing the magnitudes of gravitational constant and strong coupling constant
Authors: UV Satya Seshavatharam , S Lakshminarayana 
Published: February 2015

In the earlier published papers the authors suggested that, â€œMagnitude of the unified force can be assumed to be equal to the classical or astrophysical force limit . Strength of any interaction can be defined as the ratio of the operating force magnitude and the magnitude of . If strength of the Schwarzschild interaction is assumed to be unity, then weak interaction strength seems to be â€˜squared Avogadro numberâ€™ times less than the Schwarzschild interaction. The characteristic atomic force can be represented by â€. Thinking in this way, atomic gravitational constant can be expressed as Â With current atomic physical constants and with the assumed two new grand unified back ground numbers analytically - value of Â can be fixed for 10 digits and can be verified. Inverse of the strong coupling constant can be considered as the â€˜natural logarithm of square root of ratio of gravitational and electromagnetic force ratio of down quark mass where the operating gravitational constant is squared Avogadro number times the gravitational constantâ€™. Finally an attempt is made to fit and understand the mystery of Up and Down quarks, nuclear stability, and nuclear binding energy. For medium and heavy atomic nuclides, at the stable mass number, nuclear binding energy seems to be equal to the sum of rest energy of Â up quarks and Â down quarks.

Allomorphs of French de in coordination: a reproducible study
Authors: Zuraw Kie 
Published: February 2015

Abstract
It is known that French de ‘of’ can take wide scope in coordination – that is, the coordination can optionally be reduced by omitting the second de: de X et/ou (de) Y, meaning roughly ‘of X and/or (of) Y’. De has an allomorph d’ that is used when the following word begins with a vowel. This paper shows, using a large written corpus, that the two allomorphs, de and d’, do not behave the same when it comes to reduction/wide scope. Two main factors seem to be at play: resistance of the d’ allomorph to taking wide scope, and hiatus avoidance between et/ou (which are both vowel-final) and a following vowel-initial word. The existence of phonological factors that affect reduction rate implies that the grammar and/or processing architecture must retrieve some phonological information about X and Y before the final “decision” about reduction is made– or that the phonology is powerful enough to delete the second de on its own. This paper also aims to make a methodological contribution to reproducibility. The web materials accompanying the paper (scripts, documentation, and intermediate-stage data files, available at TROLLing, the Tromsø Repository of Language and Linguistics, opendata.uit.no/dvn/dv/trolling) allow the reader to reproduce all the steps of the data processing analysis, starting from a publicly available corpus.

Line Shape Analysis of Spin Echo Signals in Cubic Solids
Authors: Mehring M. , Kanert O. 
Published: February 2015

Abstract
In the case of static magnetic dipolar and electric quadrupolar interactions (inhomogenous broadening) the dependency of the spin echo height at time t = 2τ after a π/2-τ-β pulse sequence on the rotation angle ß of the second rf-pulse is calculated for the spins I=3/2, 5/2, 7/2, 9/2. For each spin I an optimum rotation angle βopt is found out for which the spin echo signal has a maxi­mum. From the measured spin echo lineshape the distribution function of the quadrupole distortion in a solid can be determined. The mean quadrupole distortion can be obtained from the echo width. Detailed calculations in the case of Gaussian and Lorentzian distribution functions are presented.

Radioaktive Isotope als Luftmassenindikatoren II. Die Produktion von P33
Authors: Hartwig S. , Sittkus A 
Published: February 2015

Abstract
Discussions on concentration measurements of the isotopes Be7, P32 and P33 in ground level air give rise to false conclusions about airmass exchange in the atmosphere if the measured P33 data are used as a means of characterisation. The reason for this lies in too low a production rate for P33.
The analysis gives a yield of 5.1·10 -2 (±10% the yields for P33 and P32 are equal.

Direct Photodisintegration of 9Be in the Low and Sub-Giant Resonance Energy Region
Authors: Aurdal Terje 
Published: February 2015

Abstract
Photodisintegration cross sections for the reaction 9Be(γ,n) 8Be with photonenergies varied from threshold to about 17 MeV are calculated. As nuclear model is assumed a single particle shell model where the valence neutron outside the 8Be core is feeling a spherical field. The core state is assumed to be a mixture of the ground (0+) and the first excited (2+) state of the 8Be nucleus. The total cross sections are splitted up according to the different contributing reaction channels. The radial wave functions in initial as well as final states are of the Saxon-Woods type.

Experimentelle Untersuchung der Rayleigh-Taylor-Instabilität eines rotierenden Wasserstoff-Lichtbogens im axialen Magnetfeld
Authors: Döbele H 
Published: February 2015

Abstract
A hydrogen arc with a hollow anode in an axial magnetic field is subjected to Rayleigh-Taylor instabilities as a result of rotation due to the radial current components at the anode. These instabilities take the form of periodic fluctuations in the light intensity emitted from the boundary regions of the arc. The modes m = 4 to m = 7 which occur in succession with increasing magnetic field are identified by measuring the signal phases in end-on observation of the arc. The rotational velocity of the arc plasma is determined spectroscopically and comparison is made with the non-dissipative MHD theory, which yields growth rates ∼

.The deviations from this theory that were observed in this experiment are ascribed to dissipative effects.
Diffusion von In und Cu in ZnS-Einkristallen
Authors: Nelkowski H. , Bollmann G. 
Published: February 2015

Abstract
The diffusion of In and Cu in ZnS single crystals was investigated by means of radioactive tracers. The diffusion constant Do and the activation energy EA of the diffusion equation D = D0 · exp(- EA/kT) were determined by analysing the temperature dependence of the concentration profiles. The result for ln EA = 2,2 eV, D0 = 30cm2 s-1) is interpreted as a diffusion via Zn vacancies and that for Cu (EA - 0,79 eV, D0 = 2,6 · 10-3 cm2 s-1) as a diffusion via interstitial sites which probably is influenced by Zn vacancies. - Preceding doping with In significantly retards the Cu diffusion, consistent with the model of Cu-In pair formation. The reasons for some deviations of the experimental data from the calculated concentration profiles are discussed. - Diffusion measurements with high Cu-concentrations yield a Cu-solubility of 300 ppm at 840 K and 1000 ppm at 950 K.

Abstract
The influence of the electric field on the thermally stimulated currents (TSC) in polycrystalline trigonal selenium is investigated. The field strength is varied from 12 V cm-1 to 1500 V cm-1 , and the temperature from 110°K to 270 °K with a heating rate of 0.03 °K s _1 . The observed oscillations of the TSC curves suggest a broad spectrum of traps (trap depth from 0.125 to 0.208 eV) which could be associated with oxygen impurities.
The Functional Method in the Theory of Real Gases
Authors: Lux E. 
Published: February 2015

Abstract
The relations of the theory of real gases which have first been derived by Mayer and his co-workers can be obtained in a simple way by the functional method. In this case the assumption of the pairwise additivity of the intermolecular potential can be dropped. Apart from some new relations for distributions functions the expansion of the direct correlation functions is obtained as a power series in density with coefficients consisting of integrals over Husimi functions.

On Light Scattering by Polyatomic Fluids
Authors: Hess S. 
Published: February 2015

Abstract
"Scattering equations" are derived which relate the spectrum of the light scattered from a poly-atomic fluid to the spectral functions of the fluctuating spherical (scalar) and anisotropic parts of the electric permeability tensor. The influence of a constant external (electric or magnetic) field is considered. For a gas of linear molecules, it is shown that the fluctuations leading to the depolarized Rayleigh light scattering are fluctuations of the mean (2nd rank) tensor polarization of the rotational angular momenta of the molecules. Furthermore, the fluctuations associated with the rotational Raman scattering are expressed by fluctuations of the mean values of (2nd rank) tensor operators which induce transitions between the rotational levels of a molecule.
Chemisch induzierte Kernpolarisation von Phenylhalogeniden bei der Photolyse von Aroylperoxiden
Authors: Lehnig M. , Fischer H. 
Published: February 2015

Abstract
By a flow technique chemically induced nuclear polarization is observed in the NMR-spectra of phenylhalides formed during photolysis of aroylperoxides in solution. The main features of the polarization are quantitatively explained by dynamic nuclear polarization (CIDNP) of protons in the intermediate phenyl radicals. Some details however indicate that a second polarization mechanism is also present. This mechanism leads to a multiplet-effect type polarization and operates presumably during bond fromation in the radical reactions. Some results on the magnetic field dependence of the nuclear polarizations are given.
Notizen: On the Beta Decay of 237 Pa
Authors: Egidy T. , Morinaga H. , Lingeman E. , Polak P. 
Published: February 2015

Abstract
There is a discrepancy on the decay of 237 Pa to 237 U in the literature. CRANE and IDDINGS 1 determined a half life of 10.5 ± 1 min, PATE and POSKANZER 2 found 10 min and TRAUTMANN, DENIG, KAFFRELL and HERR-MANN 3 -4 measured 8.7 ± 0.2 min. But TAKAHASHI and MORINAGA 5 give a value of 39 + 3 min. In order to solve this problem the experiment of Takahashi and Morinaga was repeated. Natural U308 was irradiated for 30 min with bremsstrahlung of the IKO electron linear accelerator (EVA) at Amsterdam (electron en-ergy 50 MeV, electron current 5 //A). 237 Pa is expect-ed to be produced by the reaction 238 U(7,p) 237 Pa. The chemical procedure suggested by NAKAI and YAJIMA 5 -6 was used to remove the fission products.
On the Behavior of Short-lived Cosmic Ray Produced Nuclides in the Lower Atmosphere
Authors: Roedel Walter 
Published: February 2015

Abstract
Some aspects of short-lived cosmic ray produced nuclides in the lower atmosphere, especially of Na24 , and their qualities as tracers for atmospheric motion are studied. The Na24 production rate has been estimated. The distribution of this nuclide as a function of altitude in the lower atmosphere has been described by a steady state eddy diffusion model. Measurements of Na24 in ground-level air have been carried out. The measured activities varied from 0.07 ·10-3 to 0.28·10-3 dpm/m3 . These figures are in good accordance with the calculated values for reasonable diffusion parameters.
Calculations suggest that CRP-nuclides with life-times in the order of a day are useful as tracers for atmospheric motions in the range of eddy diffusion coefficients of about 5·104 to several 106 cm2 sec-1 , and for altitudes below four of five kilometers.
Furthermore some relations between the specific radioactivity of rainwater and the specific activity of cloud-level air, with special respect to short-living CRP-nuclides are found. The evaluation of some measurements of Na24 activity in rain water shows good consistency between real atmospheric conditions and calculated values.

Negative Ionen durch Elektronenstoß an 2-Methoxy-2-hydroperoxy-propan
Authors: Jäger K. , Henglein A. , Doumont M. 
Published: February 2015

Abstract
Electron attachment to 2-methoxy-2-hydroperoxy propane often leads to a breakage of the 0 - 0 bond. The resulting ion CH3OC (CH3) 2O- carries excess energy and frequently dissociates either into CH2C(CH3)O- and methanol or HC(CH3)2O- and formaldehyde. In addition, a methyl group may be split from the methoxy group. The resulting ion -OC(CH3)2O2H has a high electron affinity (probably more than 3 eV). Other processes occurring frequently are the loss of H2 to produce C4H8O3
- and the formation of O2
-. Many other ions with low abundances have also been observed.
Potential Distribution in a Two-emitter Diode
Authors: Troppmann Manfred 
Published: February 2015

Abstract
The existing model of a "collisionless" alkali plasma diode is extended including the case of two incandescent plane electrodes emitting electrons as well as ions with a half-Maxwellian velocity distribution. The potential distributions within the diode space derived from this theory are examined in detail. Physically necessary conditions reduce the well-known ambiguity of solutions to a single one (with uniform plasma potential) at a given set of parameters. Further solutions, cor-responding to spatially oscillatory potential shapes which are consistent with the collisionless theory, disappear if the ion-ion collision probability within the diode plasma exceeds 0.1 per emitter distance.
In the experiment the potential distributions are scanned using a new electron beam probing technique. The results agree with theory.
Abschätzung der für die Ionenextraktion wichtigen Parameter der Raumladungsschicht

Published: February 2015

Abstract
Ions extracted from a plasma often have to pass a space charge existing in front of the container wall. If collisions occur within the sheath, both, the ion composition and the extraction efficiency may heavily be influenced.
The parameters of interest are the extension and the field strength of the sheath. A theory is presented by which these quantities can be calculated.
The theory holds for a positive space charge, the orifice being biased negativ with respect to the plasma potential.
Numerical results are given concerning a weekly ionized nitrogen plasma.
Ein Verfahren zur Berechnung der Elektronen-Populationen in großen Molekülen unter Berücksichtigung aller Elektronen

Published: February 2015

Abstract
Es wird gezeigt, daß bei Verwendung eines minimalen Basissatzes schon allein aus der Diago-nalisierung der Uberlappungsmatrix des Basissatzes exakt die gleichen Daten für die Population Analysis resultieren wie bei vorangegangener SCF Prozedur.
Daraus folgt, daß die zur Berechnung der Elektronen-Population eines Moleküls nötige Rechen-zeit auf einen kleinen Bruchteil der Rechenzeit für SCF-Rechnungen gesunken ist und daß die maximale berechenbare Anzahl der Elektronen um ein Vielfaches gestiegen ist. Dieses Verfahren ist für Slater-Funktionen als Basis ebenso brauchbar wie für Gauß-Orbitale.

Abstract
Two-Group neutron transport theory is applied to critical problems in plane and spherical geometry. The neutron flux and the density transform for plane and spherical geometry respectively are expanded into singular eigenfunctions of the transport equation. With aid of the theory of singular integral equations the problem is reduced to one Fredholm integral equation for the expansion coefficients. The critical equations are presented as additional conditions.
Zur Nukleon-Nukleon-S-Streuung mit Hilfe von Einbosonaustausch-Potentialen
Authors: Trübenbacher E. 
Published: February 2015

Abstract
An attempt is discussed to parametrize the low-energy nucleon-nucleon S-scattering data by a non-relativistic Potential corresponding to the exchange of quantum numbers JP, with mass and coupling constants of a fictive "meson" as parameters. Whereas 1S-scattering presents no difficulties, a final decision about the usefulness of the potentials was prevented by the instabilities of the numerical integrations in case of 3S-scattering with respect to a unitarity test built into the computer programme. As a by-product, a multipole expansion of the one boson exchange potential is given in analogy to electrostatics.
