Abstract
We consider the secular behavior of shell-model configuration (partial) densities. When configuration densities are characterized by their moments, one often finds large third moments, which can make suitable parameterization of the secular behavior problematic. We review several parameterizations or models, and consider in depth three specific models: Cornish-Fisher, binomial, and modified Breit-Wigner distributions. Of these three the modified Breit-Wigner provides the best secular approximation to exact numerical configuration densities computed via full diagonalization from realistic interactions.
