Description

Abstract Two programs are developed for the purpose of algebraic calculation of angular momentum coupling. The first program algebraically carries out the summation of products of many Clebsch-Gordan coefficients with respect to the magnetic quantum numbers, and the second one the summation of products of many 6-j symbols with respect to the azimuthal quantum numbers. All are done by symbolic manipulation. Title of program: KENTARO/KENJIRO Catalogue Id: ACGB_v1_0 Nature of problem The computer programs, KENTARO and KENJIRO, allow algebraic calculation of the angular momentum coupling. The first program can execute the summation of products of many Clebsch-Gordan coefficients with respect to the magnetic quantum numbers, and the second one the summation of products of many six-j symbols with respect to the azimuthal quantum numbers. Versions of this program held in the CPC repository in Mendeley Data ACGB_v1_0; KENTARO/KENJIRO; 10.1016/0010-4655(92)90135-L This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
