We investigated the development and breaking of the dineutron correlation in ${}^{10}\mathrm{Be}$ by analyzing the elastic and inelastic scatterings with a framework combining the microscopic structure and reaction models. For studying the structure, the ${}^{10}\mathrm{Be}$ nucleus was constructed under the assumption of a four-body ($\alpha +\alpha +n+n$) cluster model. In this paper, we focused on the change in 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 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 $E/A=$ 59.4 and 200 MeV. Although the $0_1^{+}$ and $2_1^{+}$ 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 $2_2^{+}$ 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 $2_2^{+}$ state of ${}^{10}\mathrm{Be}$.

非弹性散射的剧烈变化取决于 Be10 中双中子相关性的发展

我们研究了双中子相关性的发展和破坏 ${}^{10}是$通过结合微观结构和反应模型的框架分析弹性和非弹性散射。为了研究结构，${}^{10}是$ 核是在四体假设下构建的（$\alpha +\alpha +n+n$) 集群模型。在本文中，我们重点介绍了内部结构的变化$0_1^{+}$, $2_1^{+}$， 和 $2_2^{+}$当自旋轨道相互作用的强度发生变化时的状态。内部结构，包括能量、半径和跃迁强度等各种物理量，受到自旋轨道相互作用强度的极大影响。特别是，双中子相关性的发展和破坏受自旋轨道强度的控制。内部结构的差异可以通过将获得的波函数应用于具有质子目标的弹性和非弹性散射$乙/\mathrm{一种}=$59.4 和 200 MeV。虽然$0_1^{+}$ 和 $2_1^{+}$状态受核结构计算的自旋轨道强度影响显着，弹性和非弹性截面没有太大影响。另一方面，非弹性截面$2_2^{+}$状态在很大程度上取决于结构计算的自旋轨道强度。因此，我们发现了一种方法，可以根据双中子团簇结构对非弹性截面的敏感性来测量其发展程度。$2_2^{+}$ 的状态 ${}^{10}是$.
