# Generalized fractional parentage coefficients for shell-model calculations

## Description

Title of program: GFPCM Catalogue Id: AADY_v1_0 Nature of problem In a space defined by several single-particle orbitals anti-symmetric states for any n-fermion system can be expanded in terms of states which are antisymmetric only with respect to the first m and the last (n-m) particles. These (m, n-m) expansion coefficients, the Generalized Fractional Parentage Coefficients (gfpc), can then be used to determine easily the matrix elements of any m-body operator. The states are classified according to C^n which denotes the distribution of the n particles among t ...
