The UCL distorted wave code

Abstract The DW code of University College London computes collision strengths and reactance matrix elements in LS coupling for excitation of atoms and positive ions by electron impact in a partial wave expansion. A multiconfigurational target serves as the scatterer; the partial waves are central field solutions to a distorted wave (DW) approximation. The DW program is run by linking two source codes: program COLALG and a modifying module called DWMODS. In stand-alone mode COLALG cr... Title of program: UCLDW Catalogue Id: ADJG_v1_0 Nature of problem Collision strengths for electron-impact excitation of neutral atoms and positive ions are computed in the distorted wave approximation (DW) [1]; K matrix output is readily processed by JAJOM [2], yielding collision strengths between finestructure levels. Versions of this program held in the CPC repository in Mendeley Data ADJG_v1_0; UCLDW; 10.1016/S0010-4655(98)00082-4 This program has been imported from the CPC Program Library held at...
