Abstract

I investigate $^{10}$B+$\alpha$ cluster states of $^{14}$N with a $^{10}$B+$\alpha$ cluster model. Near the $\alpha$-decay threshold energy, I obtain $K^\pi=3^+$ and $K^\pi=1^+$ rotational bands having $^{10}$B($3^+$)+$\alpha$ and $^{10}$B($1^+$)+$\alpha$ components, respectively. I assign the band-head state of the $K^\pi=3^+$ band to the experimental $3^+$ at $E_x$=13.19 MeV of $^{14}$N observed in $\alpha$ scattering reactions by $^{10}$B and show that the calculated $\alpha$-decay width is consistent with the experimental data. I discuss an $\alpha$-cluster motion around the $^{10}$B cluster and show that $^{10}$B+$\alpha$ cluster states contain significant components of a linear-chain 3$\alpha$ configuration, in which an $\alpha$ cluster is localized in the longitudinal direction around the deformed $^{10}$B cluster.
