Abstract: On the basis of the j-j coupling shell model, the nuclear energies in the 2s1/2 and 1d3/2 shells are given by linear combinations of the parameters expressing the nuclear and Coulomb interaction energies in two-nucleon states, the single nucleon energies in 2s1/2 and 1d3/2 shells and the Coulomb interaction energies of a single proton in 2s1/2 and 1d3/2 shells with the closed shells. The best values of these parameters are determined by a least squares fit to the experimental binding energy data. The mean deviations are very small, and this shows the adequacy of the shell model in the ground states of these nuclei. By using these values of parameters the excitation energies are calculated, and it is shown that in some excited states configuration interactions seem to be important. The two-body force required to give the best fit with the interaction energies in two-nucleon states is discussed.
