Coulomb C2 and C4 form factors with core-polarization effects to 2+ and 4+ states in 18O and 20,22Ne have been studied using shell model calculations. The two-body effective Wildenthal interaction and universal sd-shell interaction A (USDA) are used for sd-shell orbits. Corepolarization effects are calculated using the Coulomb valance Tassie model (CVTM) and Bohr–Mottelson (BM) collective model. Some wave functions of the radial single-particle matrix elements have been calculated with harmonic oscillator (HO), Wood–Saxon (WS), and SKX potentials. The inclusions of core-polarization effects give good agreements with experimental data as comparing with model space calculations. The results for different potentials are compared.
