Possible existence of a ^7_ΣLi bound state(Microscopic Cluster Models of Light Nuclei and Related Topics)

抄録

We investigate the possible existence of a ^7_ΣLi bound state within the frame of the microscopic α+"2N"+Σ cluster model by using the effective Σ-N interaction which reproduces the experimental binding energy and width of ^4_ΣHe. One bound state of ^7_ΣLi is found with about 1.5 MeV binding energy and about 4.6 MeV width.
