چکیده
We investigate the role of tensor correlation on the structures of He and its effect on the doublet splitting in He. We perform a configuration mixing calculation in the shell model type bases to represent the tensor correlation for He. It is found that our model describes the characteristics of the tensor correlation, which is represented by an admixture of the 0s1/2 configuration with a spatially modified 0p1/2 orbit. For He, we solve a coupled OCM equation for an extended He+n model, while taking into account the tensor correlation in the He cluster. It is shown that the tensor correlation produces the Pauli blocking, in particular, for the J = 1/2− state, and its effect causes about half of the p-wave doublet splitting in He. This indicates that the strength of the effective spin-orbit interaction should be reduced by about half from the conventional one. We obtain a reliable He-n interaction, including the tensor correlation, which further improves the behavior of the dand f -wave phase shifts in the He+n system.
