A new version of CFPSIB: fractional parentage of an identical boson system

Abstract
A new version of the program CFPSIB is introduced. Using the same recurrent formula as that used in the program CFPSIB, but a different calculation procedure, the fractional parentage coefficients (CFPs) of an identical boson system with well-defined seniority can be evaluated by this new program. It is shown that this new version (named RCFPSIB) is more efficient than the program CFPSIB, especially for a system including a relatively large number of bosons, each with higher angular momentum ...

Title of program: RCFPSIB
Catalogue Id: ACGW_v2_0 [ADAA]

Nature of problem
The program calculates all the coefficients of fractional parentage (CFP)[1] of identical boson system, by using the recurrent relations[2] with well-defined seniority. CFP's are the expansion coefficients of symmetrized n-body wave functions in terms of the symmetrized (n-1)- body wave functions and the wave function of the nth boson. It is of fundamental importance in constructing a many-boson wave function with well-defined permutational symmetry and total angular momentum, and in calculating ...
