Coulomb form factors for E0 transition in 18O are discussed taking into account core-polarization effects. These effects are taken into account through the collective model of Tassie and also through a microscopic perturbation theory including excitations up to 2p1f shell. Space wave model functions defined for the orbits 1 and 2125O nucleus has been the subject of extensive theoretical and experimental studies, which received much attention in last decade [Alex Brown et.al.2005]. The 18O system contains two neutrons in addition to the16O core distributed in the sd – shell. d1 are obtained from the diagonalization of the interaction Hamilonian of Wildenthal. The calculations include the 0 2state with excitation energies3.6337MeV. The core – polarization effects which incorporate the ollective model of Tassei describe the data very well for this state.

Realistic Interaction

The longitudinal and the transverse electron scattering form factors for 6Li, 9Be, 11B and 12C nuclei have been studied with and without core polarization effects using shell model calculations. The psdmwk is used as effective interaction for psd-shells. The core-polarization effects are calculated in the first-order perturbation theory including excitations up to 4ħω using the Michigan three-range Yakawa M3Y as a realistic interaction. The wave functions of radial single particle matrix elements have been calculated with harmonic oscillator potential. For all nuclei under studying, Comparison between experimental and theoretical calculations show that the form factors with core-polarization effect calculations give good consistency with experiment data. So we concluded that the large scale model space enhanced the results to become closed to the experimental data.

Reasonable Description

Shell model and core polarization (CP) effects have been used to calculate the transverse and longitudinal electron scattering form factors for 7Li and [Formula: see text]B nuclei. The calculations considered one particle–one hole excitation up to 12[Formula: see text][Formula: see text]. This manner seems to be essential for obtaining the best explanation for empirical results. Therefore, adding the excited states up to 12[Formula: see text][Formula: see text] gives a reasonable description for transverse and longitudinal form factors. Furthermore, with these calculations, it is possible to get a very close location of diffraction minimum, and the behavior of the momentum transfer is described properly at the high configuration for 7Li compared with 6[Formula: see text][Formula: see text] energy.
