Numerical results of the deuteron problem which were carried out by Illiac computor at the University of Illinois are presented for our potential derived in our former paper (part I) and the one derived by Taketani et al. These potentials, and also the one recently derived by Brueckner and Watson have the tensor force of right sign of almost the same magnitude, but they are quite different from each other with respect to their central parts: Taketani's is strongly repulsive, ours weakly attractive and Brueckner and Watson's strongly attractive. The radius of hard core was chosen as 0.3, 0.383, and 0.466 in units of meson Compton wave length. Firstly the numerical factor multiplying the potential is adjusted so as to give the correct binding energy. Then other quantities are calculated. The numerical results show that the relative weight of central force to tensor one in our potential is too small because ours gives too large quadrupole moment and D-state probability of approximately three or four times as large as the empirical ones. In Taketani's case the deuteron cannot bind, because the repulsive central force is too large compared with the tensor one. Thus we can conclude that the attractive central force at least of the same order of magnitude as the tensor one is difinitely necessary in order to obtain the agreement with empirical data in deuteron problem.
