The effect of core polarization on longitudinal form factors in 10B

Abstract

Electron scattering Coulomb form factors for the single-particle quadrupole transitions in the p-shell 10B nucleus have been studied. Core polarization effects are included through a microscopic theory that includes excitations from the core orbits up to higher orbits with 2ℏω excitations. The modified surface delta interaction is employed as a residual interaction. The effect of core polarization is found essential in both the transition strengths and momentum transfer dependence of form factors, and gives remarkably good agreement with the measured data with no adjustable parameters.
