title: Automatic generation of tree level helicity amplitudes

description: Abstract The program MadGraph is presented which automatically generates postscript Feynman diagrams and Fortran code to calculate arbitrary tree level helicity amplitudes by calling HELAS[1] subroutines. The program is written in Fortran and is available in Unix and VMS versions. MadGraph currently includes standard model interactions of QCD and QFD, but is easily modified to include additional models such as supersymmetry. Title of program: MadGraph Catalogue Id: ACTX_v1_0 Nature of problem Calculation of higher order tree level Feynman helicity amplitudes which involve several external particles can require the evaluation of hundreds of Feynman diagrams. Hand coding programs to compute these amplitudes is very time consuming and error-prone. For complex problems the widely used packages based on symbolic mathematics systems either produce inefficient code or fail because of excessive memory or CPU requirements.

title: Electron scattering from quasi one-electron targets: experimental observables vs. theoretical scattering amplitudes

description: Abstract A program is presented to calculate various experimental observables as bilinear products of scattering amplitudes for impact excitation of (quasi) one-electron atoms by a spin polarized electron beam. Furthermore, it is demonstrated how experimental data for a minimum set of observables can be “inverted” to extract the scattering amplitudes. A successful and unique inversion of such data corresponds to a “complete experiment”. Title of program: ALKALI-OBSERVABLES Catalogue Id: ACVN_v1_0 Nature of problem This program calculates a large number of observables that have been defined in the literature for both unpolarized and spin polarized electron impact of atomic hydrogen or quasi one-electrons atoms and ions [1,2]. Given partially complete experimental data for some of these observables, the code can be used to "invert" these data and obtain the scattering amplitudes - up to some ambiguities which can, however, be resolved with some confidence by comparing with accurate theoretical results.

The user has a possibility of choosing among various symmetries of the nuclear HF problem for rotating or nonrotating nuclei; they vary from the non-axial parity-invariant nuclear shapes, through those also breaking the intrinsic parity, towards the least-restrictive case corresponding to only one symmetry plane.

title: REOS — A program for relaxed-orbital oscillator strength calculations

description: Abstract A spontaneous decay of an excited atomic state leads to a rearrangement of the spatial electron distribution in the atom. This redistribution concerns the entire electronic cloud and not only the active electron in an atomic transition. For many-electron atoms, rearrangement effects are naturally included if the electronic wavefunctions of the initial and final states are determined independently. The separate optimization of the atomic states, however, yields two sets of one-electron orbital... Title of program: REOS Catalogue Id: ADEJ_v1_0 Nature of problem The separate optimization of a wave function for an atomic state results in a set of electron orbitals which are not quite orthogonal to the orbitals obtained for a different state.
