Study of Resonant Structure with the Complex-Scaled Jost Function Method

抄録

We study resonant structures of unstable nuclei with a new calculational method, the Jost function method (JFM). In JFM, bound, scattering and resonant states are obtained within an unified way. We show that partial decay widths in coupled-channel systems can be obtained by using JFM. Further, JFM has an ability to solve virtual states. As a practical example, we study virtual states in ^5He and ^<10>Li with the core+n model.
