Momentum Distributions in Nuclei

Abstract

This chapter is devoted to nucleon-nucleon correlation effects on the two main ground state characteristics, nucleon momentum (n(k)) and density distributions (ρ(r)). The functional relation between them founded on the Hohenberg-Kohn theorem [7.19, 7.20], the formulation of a variational principle using both equivalent physical quantities (ρ and n), and the results of wide range of correlation methods and models of the momentum distribution in various nuclei and nuclear matter are presented in Sect. 7.1. The theoretical results for n(k) are compared with the experimental data from different reactions on 2H, 3,4He, 12C, 56Fe nuclei and with the single-particle momentum distributions in 16O and 208Pb. The problems of the nucleon momentum distribution in nuclei at finite temperatures and its dependence on nuclear deformation are also considered. Special attention is paid on the extraction of the nucleon momentum distribution from the experimental data obtained in particle-nucleus reactions.KeywordsNuclear MatterMomentum DistributionCharge Form FactorNucleon MomentumGenerator Coordinate MethodThese keywords were added by machine and not by the authors.
