Core Polarization Effects on the Inelastic Longitudinal Electron Scattering Form Factors of 48,50 Ti and 52,54 Cr nuclei

In this paper, inelastic longitudinal electron scattering form factors C2 and C4 transitions have been studied in Ti 48,50 and Cr 52,54 nuclei with the aid of shell model calculations. The core polarization transition density was evaluated by adopting the shape of Tassie model togther with the derived form of the ground state two-body charge density distributions (2BCDD s). The following transitions have been investigated; 0 1^+2→ 2 1^+2 and 0 1^+2→4 1^+2 of 48Ti , 0 1^+3→2 1^+3 and 0 1^+3→ 4 1^+3 of 50Ti, 0 1^+2→ 2 1^+2 and 0 1^+2→ 4 1^+2 of 52 Cr and 0 1^+3→ 2 1^+3 and 0 1^+3→ 4 1^+3 of 54 Cr nuclei. It is found that the core polarization effects, which represent the collective modes, are essential for reproducing a remarkable agreement between the calculated inelastic longitudinal C2 and C4 form factors and those of experimental data.
