Title of program: MRVAC Catalogue Id: ACCV_v1_0 Nature of problem A wide variety of scattering problems can be reduced to solving sets of coupled differential equations wherein the coupling can be represented as a matrix series in r^-n at large values of r. The program is designed to produce solutions of the equations at an input value r = Ro, and to calculate a K-matrix to a specified accuracy from an input R-matrix at r = Ro. Versions of this program held in the CPC repository in Mendeley Data ACCV_v1_0; MRVAC; 10.1016/0010-4655(84)90170-X This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
