title: grcννγ: Event generator for the single- and double-photon emission associated with neutrino pair-production ☆

description: Abstract A new event generator is proposed for two processes e^+ e^- →νν̄γ and e^+ e^- →νν̄γγ where νν̄ includes all the neutrino species. The exact matrix elements of single- and double-photon emission, generated by the GRACE system, are convoluted with the QED parton shower (QEDPS) to deal with the initial state radiations (ISR). It is pointed out that a careful treatment is required to avoid the double counting of the radiative photons between the matrix elements and the ISR part. A detailed compar...

title: A fast parallel code for calculating energies and oscillator strengths of many-electron atoms at neutron star magnetic field strengths in adiabatic approximation

description: Abstract We have developed a new method for the fast computation of wavelengths and oscillator strengths for medium-Z atoms and ions, up to iron, at neutron star magnetic field strengths. The method is a parallelized Hartree-Fock approach in adiabatic approximation based on finite-element and B-spline techniques. It turns out that typically 15-20 finite elements are sufficient to calculate energies to within a relative accuracy of 10^(-5)in 4 or 5 iteration steps using B-splines of 6th order, with ...

description: Abstract The program mcci (Monte Carlo configuration interaction) is a simple to use and efficient means for performing configuration interaction (CI) calculations. As with all forms of CI, the basic problem is how to select new configurations for the expansion of the wavefunction and this is the issue addressed by mcci. The mcci program selects configurations through a Monte Carlo generation procedure and then iteratively refines the wavefunction. As a consequence, a compact CI vector results as oppo...
