Inelastic longitudinal C2 form factors for + ® +1 1 0 1 2 1 and + ® +1 2 0 1 2 1
transitions in open sd shell nuclei (22Ne, 26Mg and 30Si ) are discussed taking
into accounot the effects of core polarization. These effects are calculated using
the shape of Tassie model together with our derived form of the ground state twobody
charge density distribution (2BCDD). Remarkable agreements are obtained
between the calculated inelastic longitudinal C2 form factors and those of
experimental data.
