Title: Inclusion of nonspherical components of the Pauli blocking operator in (p,p{sup '}) reactions

Abstract

We present the first calculations of proton elastic and inelastic scattering in which the Pauli blocking operator contains the leading nonspherical components as well as the usual spherical (angle-averaged) part. We develop a formalism for including the contributions to the effective nucleon-nucleon interaction from the resulting new G-matrix elements that extend the usual two-nucleon spin structure and may not conserve angular momentum. We explore the consequences of parity conservation, time-reversal invariance, and nucleon-nucleon antisymmetrization for the new effective interaction. Changes to the calculated cross section and spin observables are small in the energy range from 100 to 200 MeV.
