The effect of core polarization on longitudinal form factors in $^{10}$B

TL;DR

This paper investigates how core polarization influences the electron scattering Coulomb form factors in the $^{10}$B nucleus, demonstrating that including these effects yields results that closely match experimental data without adjustable parameters.

Contribution

It introduces a microscopic theory incorporating core excitations up to 2$ ext{h}ar{ extomega}$ to accurately model form factors in $^{10}$B.

Findings

Core polarization significantly affects transition strengths.

Including core polarization improves agreement with experimental data.

No adjustable parameters are needed for the model.

Abstract

Electron scattering Coulomb form factors for the single-particle quadrupole transitions in $p$-shell $^{10}$B 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 2$\hbar$$\omega$ excitations. The modified surface delta interaction (MSDI) 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 a remarkably good agreement with the measured data with no adjustable parameters.
