本文用壳模型方法研究了~ 4 He的张量关联特性。我们处理张量力明确执行的配置混合计算在2 p2 h的基础上，包括单粒子状态到中间高角动量。我们采用高斯展开的方法来定量描述单粒子态的空间收缩，以优化张量关联。我们能够描述的完整强度的张量相关的4 He在壳模型类型的方法实现收敛。我们称这个模型为张量优化壳模型。结果表明，在4 He中，由于张量算符的特征，三种特定的2 p2 h组态与（0 s）4组态强耦合.
We study the characteristics of the tensor correlation in 4 He using a shell model type method. We treat the tensor force explicitly by performing a configuration-mixing calculation in the 2p2h basis and include single-particle states up to intermediately high angular momenta. We adopt the Gaussian expansion method for the quantitative description of the spatial shrinkage of the single-particle states to optimize the tensor correlation. We are able to describe the full strength of the tensor correlation for 4 He in the shell model type method by realizing convergence. We call this model the tensor-optimized shell model. It is found that in 4 He, three specific 2p2h configurations are strongly coupled with the (0s) 4 configuration due to the characteristic features of the tensor operator.
