Admixture of higher multi-$\hslash \omega$ configurations in the calculation of electron scattering form factors of some 1p-shell nuclei

Özet

A semi-microscopic approach that modifies the 1p-shell model wave functions through the admixture of higher p-shells configurations from multi-$\hslash \omega$ model space is submitted in this work. The longitudinal form factors of C2 transitions in $^7Li$ and $^{15}N$, and the transverse form factors of M1 transition in $^{12}C$ 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.
