Signatures of Density Dependence in the Two-Nucleon Effective Interaction near 150 MeV

Abstract

Definitive evidence for strong density dependence in the two-nucleon effective interaction is noted in inelastic ($p$,${p}^{\ensuremath{'}}$) differential cross section and polarization data for ${E}_{p}\ensuremath{\sim}150$ MeV. These effects are quite sensitive to variations in the nuclear medium and are well described, for inelastic scattering, by the local-density approximation with use of density-dependent effective interactions from nuclear matter.
