Description

Title of program: ROOT Catalogue Id: ABVN_v1_0 Nature of problem A subroutine package is provided for the exact evaluation of vector coupling coefficients (Wigner 3j, 6j and 9j symbols) and for exact arithmetic involving these and related quantities. The main program supplied with the package can be used interactively like a calculator working in Reverse Polish Notation, to evaluate vector-coupling coefficients and to perform simple arithmetic on them. Versions of this program held in the CPC repository in Mendeley Data ABVN_v1_0; ROOT; 10.1016/0010-4655(80)90040-5 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
