The nuclear density of states and the role of the residual interaction

Abstract

We discuss the role of mean-field and moment methods in microscopic models for calculating the nuclear density of states (also known as the nuclear level density). Working in a shell-model framework, we use moments of the nuclear many-body Hamiltonian to illustrate the importance of the residual interaction for accurate representations.
