Description
We investigate the Coulomb sum rule of 40Ca for the momentum transfer q=2.0 fm-1 in the framework of traditional nuclear many-body theory, namely, by using the G-matrix and the extended RPA theory. We have evaluated the one-body part (total charge Z) and the two-body part (two-body correlation function) of the Coulomb sum rule separately. A considerable part of the missing charge in the existing experimental data is found to be explained mainly by the ground state correlations induced by the tensor force. It was also found that the one-body part (charge Z) is not exhausted in the existing experimental data. (orig.)
