Microscopìc Study of the Response of Nuclear Matter

Abstract

The correlated random-phase approximation (CRPAj), which provides a description of the linear response and elementary excitations of nuclear matter, is summarized. The density-density response functions of symmetrical nuclear matter and pure neutron matter are calculated using a local version of CRPA1 (LCRPA) based on the v2 model nucleon-nucleon interaction. Although simple, the calculation establishes some significant qualitative trends. It constitutes a prelude to calculations of response functions of realistic nucleon matter both with CRPA1 and with theories that go beyond it.
