Description
Cluster formation is a universal phenomenon found in hierarchical layers of matter. The variation of clustering in the isotope chain toward the neutron drip-line is one of such interest. Recently, the negative correlation between the $\alpha$ cluster formation and neutron number in Sn isotopes has been reported by the experiment using the $(p,p\alpha)$ reactions showing the trend opposite to that of Be and B isotopes predicted by theoretical calculations. Although the observed charge radii of Be and B isotopes seem to support the conjecture of the development of clustering toward the neutron drip-line, those radii themselves are not a physical quantity that can directly probe the cluster structure. Here, we have investigated the cluster formations in Be and B isotopes to clarify the possible clustering toward the neutron drip-line using antisymmetrized molecular dynamics (AMD). It has been shown that the sum of $\alpha$, $^{6}\mathrm{He}$, and $^{8}\mathrm{He}$ spectroscopic factors increases toward the neutron drip-line, which is consistent with the previous studies.
