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 ω 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.

“…The effect of the core polarization on the form factors is based on a microscopic theory, which combines shell-model wave functions and configuration with higher energy as particle-hole perturbation expansion. The reduced matrix element of the electron scattering operator   Tˆ is expressed as a sum of the fp-model space (fp) contribution and the core-polarization (cp) contribution, as follows (Radhi et al,2001)…”

“…These effects are found essential for obtaining a quantitative agreement with the experimental data (Yokoyama et al,1989;Sato et al,1994). A microscopic model (Radhi et al,2001;Radhi,2003) has been used in order to study the core polarization effect on the longitudinal form factors of fp-shell nuclei. The auther adopted the first order core polarization to calculate the C2 form factors of the fp-shell nuclei.…”

The form factor for inelastic electron scattering to 2 + and 4 + states in 50,52,54 Cr have been studied in the framework of shell model. The calculation is performed in the (0f7/2,1p3/2,0f5/2,1p1/2). Longitudinal C2 and C4 multipolarity are investigated for these states. Core polarization effect are included through the first order perturbation theory and the matrix element are calculated with MSDI. The inclusion of core polarization leads to an enhancement of the calculated form factor, improving good agreement with experimental data.

“…Radhi et al [7] studied the quadrupole Coulomb form factors (C2) transitions for p-shell nuclei, including the core-polarization effects excited up to 6ħω. They have verified that the effects of corepolarization are fundamental in both the momentum transfer and transition strengths and their results were in good agreement with no adjustable parameters.…”
