“…In another study carried out by Selman et al [13], the form factor for inelastic electron scattering to 2+ and 4+ states in 50,52,54 Cr have been examined by the use of the shell model. Longitudinal C2 and C4 multipolarity are studied for these states.…”

Many effective interactions have been developed to provide a better understanding of the nuclear properties by starting with the realistic nucleon-nucleon (NN) interaction and using quantum-mechanical many-body theory. In this study, the calculations of inelastic longitudinal electron scattering form factors for C2 and C4 transitions have been examined in 58,60 Ni isotopes. The F5PVH effective interaction for the fp-shell is used with the nucleon-nucleon realistic interaction Michigan three-range Yukawa and Modified surface delta interaction as a two-body interaction. Two shell model codes, CP and OXBASH for windows, have been utilized in order to obtain the results. The core polarization effects are considered as the first-order perturbation theory with the effective charge of both proton and neutron. Based on the obtained results, the effective charge along with the core effects have significantly improved the calculation in term of the agreement with the experimental data. Also, the 60 Ni nuclei tend to have a better agreement when compared to 58 Ni nuclei.

“…These effects can be considered as a polarization of core protons by the valence protons and neutrons. Core polarization effects can be treated either by connecting the ground state to the J-multipole ω  n giant resonances [4], where the shape of the transition densities for these excitations is given by Tassie model [5], or by using a microscopic theory [6][7][8] which permits one particle-one hole (1p-1h) excitations of the core and also of the model space to describe these longitudinal excitations. Comparisons between theoretical and observed longitudinal electron scattering form factors have long been used as stringent test of models of nuclear structure.…”

An expression for the transition charge density is investigated where the deformation in nuclear collective modes is taken into consideration besides the shell model transition density. The inelastic longitudinal form factors C2 calculated using this transition charge density with excitation of the levels for Cr54,52,50 nuclei. In this work, the core polarization transition density is evaluated by adopting the shape of Tassie model together with the derived form of the ground state two-body charge density distributions (2BCDD's). It is noticed that the core polarization effects which represent the collective modes are essential in obtaining a remarkable agreement between the calculated inelastic longitudinal F(q)'s and those of experimental data.

An analytical form of the ground state charge density distributionsfor the low mass fp shell nuclei ( 40  A  56 ) is derived from asimple method based on the use of the single particle wave functionsof the harmonic oscillator potential and the occupation numbers ofthe states, which are determined from the comparison between theoryand experiment.For investigating the inelastic longitudinal electron scattering formfactors, an expression for the transition charge density is studiedwhere the deformation in nuclear collective modes is taken intoconsideration besides the shell model space transition density. Thecore polarization transition density is evaluated by adopting theshape of Tassie model together with the derived form of the groundstate charge density distribution. In this work, we devote ourinvestigation on 0 3 2 3 1 1   transition of Ti 50 , 0 1 2 1 1 1   transitionof Cr 50 and 0 2 2 2 1 1   of Cr 52 nuclei. It is found that the corepolarization effects, which represent the collective modes, areessential for reproducing a remarkable agreement between thecalculated inelastic longitudinal C2 form factors and those ofexperimental data.
