Relativistic predictions of spin observables for exclusive proton knockout reactions

Abstract

Within the framework of the relativistic distorted wave impulse approximation (DWIA), we investigate the sensitivity of complete sets of polarization transfer observables for exclusive proton knockout from the 3s${}_{1/2}$, 2d${}_{3/2}$ and 2d${}_{5/2}$ states in ${}^{208}$Pb, at an incident laboratory kinetic energy of 202 MeV, and for coincident coplanar scattering angles ($28.0^{\circ }$, $-54.6^{\circ }$), to different distorting optical potentials, finite-range (FR) versus zero-range (ZR) approximations to the DWIA, as well as medium-modified meson-nucleon coupling constants and meson masses. Results are also compared to the nonrelativistic DWIA predictions based on the Schrödinger equation.
