Field-Theoretic Origin of the Isovector Central (Lane) and Spin-Orbit Potentials for Quasielastic (P,N) Reactions

  • J. V. Noble

Abstract

As several authors have pointed out,1–8 a relativistic description of nuclear one-body motion improves on the usual Schroedinger theory in several ways: First, the spin-orbit potential arises naturally from the velocity dependence of the forces,1,7,8 as does the “full-Thomas” form of the spin-orbit potential in de-formed nuclei.9 Second, the observed energy dependence of the real part of the nucleon-nucleus optical potential can be understood as mainly a relativistic kinematic effect.1,2,5,10 And third, the relativistic approach is more fundamental, in the sense that it relates the nuclear one-body potentials to the average meson fields present in nuclei.1–4,6 This note is a study of the consequences of the nuclear ρ-meson field for charge-exchange reactions, and particularly (p,n) reactions.
