A program to calculate fractional parentage coefficients for jj-coupling states with equivalent particles
Description
Abstract The n−1→n fractional parentage coefficients (FPC's) for the jj-coupling states with equivalent particles in a j shell are calculated by using the branching rules for the unitary group U(2j+1) and the recurrence formula for the FPC's. Title of program: JJFPC Catalogue Id: ACJY_v1_0 Nature of problem This Program calculates the n - 1 -> n fractional parentage coefficients (FPC's) for the jj-coupling states with equivalent particles in a j shell. The FPC's are needed in the evaluation of matrix elements for one- or two-body operators corresponding to various physical quantities in atomic or nuclear systems combined with the recoupling coefficients and the reduced matrix elements of these operators. Use of the FPC's makes one possible to remove a tedious treatment of the antisymmetrization of ...
