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 Queen's University Belfast (1969-2018)
