Gaussian polynomial method for spin-dependent level density and new formula for spin distribution
Large-scale combinatorial calculations of level densities were performed for selected nuclei using Gaussian polynomial generating function method (GPM). Contrary to the results of previous combinatorial calculations, the authors find a good agreement of the combinatorial total level densities and Bethe formula. Combinatorial GPM calculations were performed also for spin-dependent level densities and comparison is made with various algebraic formulas. On the basis of the GPM calculations the authors propose a new phenomenological spin-dependent level density formula, which in the low-spin limit reduces to the spin-dependent formula of Bethe. The new formula is for all spins factorized into the product of total level density and spin distribution function, where the spin distribution function contains an additional spin correction parameter.
