Damping of simple modes of high-energy nuclear excitations: dispersive optical models and their implementations

Abstract

Abstract. The particle-hole dispersive optical model, proposed recently to describe the main properties of high-energy particle-hole-type excitations in medium-heavy mass spherical nuclei, is briefly presented. Unique features of the model, new developments and some implementations are discussed. In applying to the description of deep-hole states, an unitary version of the single-quasiparticle optical model is also briefly presented.Dedicated to the memory of Spartak T. Belyaev
