Abstract
We investigated the development and breaking of the dineutron correlation in by analyzing the elastic and inelastic scatterings with a framework combining the microscopic structure and reaction models. For studying the structure, the nucleus was constructed under the assumption of a four-body () cluster model. In this paper, we focused on the change in the inner structure for the , , and states when the strength of the spin-orbit interaction is varied. The inner structure, including various physical quantities such as energy, radius, and transition strength, is drastically influenced by the strength of the spin-orbit interaction. In particular, the development and breaking of the dineutron correlation are governed by the spin-orbit strength. The differences in the inner structure can be manifested by applying the obtained wave functions to elastic and inelastic scatterings with a proton target at 59.4 and 200 MeV. Although the and states are significantly influenced by the spin-orbit strength of the nuclear structure calculation, the elastic and inelastic cross sections are not much affected. On the other hand, the inelastic cross section of the state depends greatly on the spin-orbit strength of the structure calculation. Thus, we discovered a way to measure the degree of the development of the dineutron cluster structure based on its sensitivity to the inelastic cross section of the state of .
