摘要: We discuss the static path plus random phase approximation (SPA+RPA) to partition function of warm finite nuclei. The method, derived from auxiliary field integral representation function, takes into account large amplitude statistical fluctuations around mean field, and is able provide an accurate evaluation thermodynamics properties within configuration spaces. present some recent improvements which include treatment repulsive terms in interaction, exact implementation canonical restricted grand ensembles with fixed number parity, response strength functions.
