Short Range Correlations and Single Particle Spectral Functions in Nuclear Matter

Abstract

The effects of short-range correlations on the single-particle spectral functions and the occupation probabilities of nuclear matter are studied. The spectral functions are calculated by solving a Dyson equation in the framework of a Selfconsistent Green’s function method. The density dependence of the depletion is discussed. The single particle spectral functions are used to calculate the dynamic structure function. The quenching and spreading observed in the quasi elastic peak of the response are related to the depletion and fragmentation of the single particle states.
