Description

Abstract The fortran 77 code system elsepa for the calculation of elastic scattering of electrons and positrons by atoms, positive ions and molecules is presented. These codes perform relativistic (Dirac) partial-wave calculations for scattering by a local central interaction potential V ( r ) . For atoms and ions, the static-field approximation is adopted, with the potential set equal to the electrostatic interaction energy between the projectile and the target, plus an approximate local exchange int... Title of program: ELSEPA Catalogue Id: ADUS_v1_0 Nature of problem The code calculates differential cross sections, total cross sections and transport cross sections for single elastic scattering of electrons and positrons by neutral atoms, positive ions and randomly oriented molecules. For projectiles with kinetic energies less than about 5 MeV, the programs can also compute scattering amplitudes and spin polarization functions. Versions of this program held in the CPC repository in Mendeley Data ADUS_v1_0; ELSEPA; 10.1016/j.cpc.2004.09.006 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
