Drastic change in inelastic scattering depending on the development of dineutron correlation in $^{10}$Be

Abstract

We investigate the development and breaking of dineutron correlation in 10 Be through the analysis of the elastic and inelastic scatterings with the framework combing microscopic structure and reaction models.For the structure side, the 10 Be nucleus is constructed with the assumption of a four-body (α + α + n + n) cluster model. Here we focus on the change of the inner structure for the 0 + 1 , 2 + 1 , and 2 + 2 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
