Densities of Excited Particle-Hole States in Physics of Nuclear Reactions

摘要

Various methods for describing the densities of particle-hole states are considered. The calculation formalism of the density of particle-hole states is considered in detail within the equidistant approximation, taking into account the Pauli principle, the finite depth of the potential well, the pairing effect the averaged energy dependence of the single-particle density, spin dependence, and the separation of particles and holes into protons and neutrons. Methods for describing the density of accessible particle-hole states of compound and final nuclei within various models of pre-equilibrium nuclear reactions are described. The influence of the energy dependence of the realistic single-particle density (continuum effect) is considered Methods for calculating the realistic density of particle-hole states, taking into account the effect of the random residual pair interaction, are considered.
