Programs for algebraic calculation of angular momentum coupling
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.
