Nature of problem:Generating the list of one-particle and two-particle coefficients of fractional parentage for the single j-orbit with isospin. | ||

Solution method:The method is based on the algorithm presented in [1] for the spectral decomposition of an antisymmetrization operator matrix Y. The coefficients of fractional parentage are the eigenvectors of a certain antisymmetrization operator matrix Y that correspond to its unit eigenvalues. | ||

Restrictions:The full sets of one-particle and two-particle coefficients of fractional parentage up to the j = 9/2 orbit; the number of particles in the higher j-orbits should be restricted. The enumeration of coefficients of fractional parentage up to the j = 15/2 orbit; the number of particles in the higher j-orbits should be restricted. | ||

Unusual features:Possibility to select subsets of one-particle and two-particle coefficients of fractional parentage for calculation. | ||

Running time:Of the order of a few seconds for lower j-orbits to hours for the complete j = 9/2 orbit calculations. | ||
