# ISICS: A program for calculating K-, L- and M-shell cross sections from ECPSSR theory using a personal computer

## Description

Abstract A versatile and fast C-language program has been developed to exactly calculate ionization and x-ray production cross sections using the ECPSSR theory. All elements and any projectile can be selected for any range of energies and energy increments. Coulomb excitation form factors are numerically calculated in the program. Comparisons are presented between program calculations and those obtained by standard procedures from other sources. The program is available in compiled form and in source ... Title of program: ISICS Catalogue Id: ADDS_v1_0 Nature of problem The cross section for atomic inner-shell ionizatin by accelerated positive ions is most commonly described by the plane wave Born approximation (PWBA) with perturbed stationary state corrections for ion-induced binding and polarization effects, Coulomb deflection of the ion's trajectory and relativity (ECPSSR). ISICS is a stand-alone package that uses Gauss-Legendre quadrature integration to obtain the form factors to calculate PWBA and ECPSSR K-, L- and M-shell cross sections for any projectile ...
