A general program to calculate atomic continuum processes using the NIEM method
Description
Abstract This paper describes a set of computer program packages NIEM which enable electron-atom and electron-ion collision cross sections to be calculated for a general atomic system described by LS-coupling. The calculations are based on a non-iterative integral equation method. Title of program: NIEM ASYM3 Catalogue Id: AAJI_v1_0 Nature of problem Reactance K-matrices at infinity are calculated from Wigner R-matrices or reactance K-matrices which are given at a radial boundary R1STOP, either by the user or are passed by NIEM NIES2. Versions of this program held in the CPC repository in Mendeley Data AAJI_v1_0; NIEM ASYM3; 10.1016/0010-4655(81)90002-3 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
