Inclusion of two-body effects in calculating nuclear level densities

The nuclear level density is normally addressed through the use of non-interactive Fermion models. These are easy to understand, involve minimal input and are efficient for making calculations. There are some questions about the use of these models off of the stability line and in regions of extreme deformation. New developments in the theory of moment methods allow better calculations involving a two-body interaction. These techniques and some results will be presented.
