| Abstract: | We propose a new theoretical approach to describe nucleus using bare nuclear interaction, in which the tensor and short-range correlations are described with the tensor optimized shell model (TOSM) and the unitary correlation operator method (UCOM), respectively. We show the obtained results of He and Li isotopes using TOSM + UCOM, such as the importance of the pn-pair correlated by the tensor force, and the structure differences in the 3/2? and 1/2? states of 5He. |
