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.
This research was supported by CAYCIT Grant No. PB85-0072-C02-00 (Spain) and by the Condensed Matter Theory Program of the Division of Materials Research of the U.S. National Science Foundation under Grant No. DMR-9002863 which also provided computer time for the calculations at the Pittsburgh Supercomputer Center. Additional support was provided in part by NATO under Grant No. RG 85/0684 and by the European Research Office of the United States Army.
