A Review of the Current Efforts of the Projected Shell Model in Nuclear Structure Physics

Abstract

The Projected Shell Model (PSM) of Hara and Sun is reviewed. This is a shell model developed for the medium to heavy systems. Although the model can be applied to a variety of collective modes, its current numerical code is primarily designed to study nuclear structure of well deformed systems, in high and low spin states. We will give a general discussion of the model and its relationship with the algebraic approaches such as the Fermion Dy namical Symmetry Model, and also show various applications to the physics of high spin spectroscopy, level statistics (or "quantum chaos"), and AI = 4 bifurcation.
