    "abstract": "We study the characteristics of the tensor correlation in $^4$He using a\nshell model type method. We treat the tensor force explicitly by performing a\nconfiguration-mixing calculation in the $2p2h$ basis and include\nsingle-particle states up to intermediately high angular momenta. We adopt the\nGaussian expansion method for the quantitative description of the spatial\nshrinkage of the single-particle states to optimize the tensor correlation. We\nare able to describe the full strength of the tensor correlation for $^4$He in\nthe shell model type method by realizing convergence. We call this model the\ntensor-optimized shell model. It is found that in $^4$He, three specific $2p2h$\nconfigurations are strongly coupled with the $(0s)^4$ configuration due to the\ncharacteristic features of the tensor operator.",
