Admixture of higher multi-hbarw configurations in the calculation of electron scattering form factors of some 1p-shell nuclei

A semi-microscopic approach that modifies the 1p-shell model wave functions through the admixture of higher p-shells configurations from multi-hbarw model space is submitted in this work. The longitudinal form factors of C2 transitions in 7Li and 15N, and the transverse form factors of M1 transition in 12C are calculated in the framework of this approach with the emphasis on the reproduction of the second lobe data. It is found that a slight contribution of the higher multi-p-shells with the 1p-shell in the modified initial and/or final states wave functions is sufficient for giving the best description to the form factors data
