INCLUSION OF 2-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 min imal input and are efficient for making calculations. There are some q uestions about the use of these models off of the stability line and i n regions of extreme deformation. New developments in the theory of mo ment methods allow better calculations involving a two-body interactio n. These techniques and some results will be presented. (C) 1997 Elsev ier Science S.A.
