An effective two-body density operator for point nucleon system folded with the two-body short range correlations (SRC's), which take account of the strong short range repulsion in the nucleon-nucleon forces, is produced and used to derive an explicit form for ground state two-body charge density distributions (2BCDD's) applicable for various closed and open shell nuclei with N=Z.

An effective two-body density operator for point nucleon system folded with the two-body short range correlations (SRC's), which take account of the strong short range repulsion in the nucleon-nucleon forces, is produced and used to derive an explicit form for ground state two-body charge density distributions (2BCDD's) applicable for various closed and open shell nuclei with N=Z. For investigating the inelastic longitudinal form factors F(q)'s, an expression for the transition charge density is studied where the deformation in nuclear collective modes is taken into consideration besides the shell model transition density.In this work, the core polarization transition density is evaluated by adopting the shape of Tassie model togther with the derived form of the ground state (2BCDD's). It is noticed that the core polarization effects which represent the collective modes are essential in obtaining a remarkable agreement between the calculated inelastic longitudinal F(q)'s and those of experimental data for 4He, 12C, 16O, 28Si, 32S and 40Ca nuclei.
