Realistic Intrinsic State Densities for Deformed Nuclei

A microscopic method for calculation of total ω(U) state densities based on a combinatorial Monte Carlo evaluation from a Woods-Saxon single-particle level (SPL) scheme at given deformation has been implemented. Residual pairing interaction can be considered in the calculations. A fast Monte Carlo algorithm is used, allowing large shell-model spaces to be studied. Intrinsic level densities for ¹⁶²Dy nucleus are calculated for various model spaces. Discussions of results relevant for Shell Model Monte Carlo calculations are presented.
