Description

Abstract We present a FORTRAN90 program GCFP for the calculation of the generalized coefficients of fractional parentage (generalized CFPs or GCFP). The approach is based on the observation that the multi-shell CFPs can be expressed in terms of single-shell CFPs, while the latter can be readily calculated employing a simple enumeration scheme of antisymmetric A-particle states and an efficient method of construction of the idempotent matrix eigenvectors. The program provides fast calculation of GCFPs ... Title of program: GCFP, parGCFP Catalogue Id: AEBI_v1_0 Nature of problem The code GCFP generates a list of two-particle coefficients of fractional parentage for several j-shells with isospin. Versions of this program held in the CPC repository in Mendeley Data AEBI_v1_0; GCFP, parGCFP; 10.1016/j.cpc.2008.06.001 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
