# A FORTRAN program for the CFPs of a boson system with F spin

## Description

Abstract A simple FORTRAN program called CFPBF calculates the fractional parentage coefficients (CFPs) of identical boson system with F spin. The program CFPBF is based on an algorithm which uses the generalized Wigner-Eckart theorem of semisimple compact Lie groups. It is not only convenient for the discussion of the role of F spin but also more efficient for the CFPs calculation in the proton-neutron interacting boson model. Title of program: CFPBF Catalogue Id: ADAH_v1_0 Nature of problem The wave functions of identical particle system possessing rotational invariance can be calculated through its fractional parentage coefficients (CFPs). Therefore the calculation of the CFPs is quite important in microphysics fields. In comparison with other presently available CFPs code, CFPBF calculates the CFPs with explicit seniority and F spin quantum numbers. It is more efficient when dealing with proton-neutron interacting boson model.
