    "abstract": "We investigate the role of tensor correlation on the structures of\n\\nuc{4}{He} and its effect on the doublet splitting in \\nuc{5}{He}. We perform\na configuration mixing calculation in the shell model type bases to represent\nthe tensor correlation for $^4$He. It is found that our model describes the\ncharacteristics of the tensor correlation, which is represented by an admixture\nof the $0s_{1/2}$ configuration with a spatially modified $0p_{1/2}$ orbit. For\n$^5$He, we solve a coupled OCM equation for an extended $^4$He+$n$ model, while\ntaking into account the tensor correlation in the $^4$He cluster. It is shown\nthat the tensor correlation produces the Pauli blocking, in particular, for the\n$J^\\pi={1/2}^-$ state, and its effect causes about half of the p-wave doublet\nsplitting in $^5$He. This indicates that the strength of the effective\nspin-orbit interaction should be reduced by about half from the conventional\none. We obtain a reliable $^4$He-$n$ interaction, including the tensor\ncorrelation, which further improves the behavior of the $d$- and $f$-wave phase\nshifts in the $^4$He+$n$ system.",
