- Shell model calculations based on large basis has been conducted to study the nuclear structure of 20Ne, 22Ne and 24Mg nuclei. The energy levels, inelastic electron scattering form factors and transition probabilities are discussed by considering the contribution of configurations with high-energy beyond the model space of sd-shell model space which is denoted as the core polarization effects. The Core polarization is considered by taking the excitations of nucleus from the 1s and 1p core orbits and also from the valence 2s 1d shell orbits into higher shells with 4~!. The effective interactions USDA and USDB are employed with sd shell model space to perform the calculation and the core polarization are calculated with MSDI as residual interaction. The calculated energy level schemes, form factors and transition probabilities were compared with the corresponding experimental data. The effect of core polarization is found very important for the calculation of B(C2), B(C4) and form factors, and gives excellent results in comparison with the experimental data without including any adjustable parameters.
