我用$^{10}$B+$alpha$聚类模型研究$^{14}$N的$^{10}$B+$alpha$聚类状态。在$alpha$衰变阈值能量附近,我得到$K^pi=3^+$和$K^pi=1^+$旋转带,分别具有$^{10}$B($3^+$)+$alpha$和$^{10}$B($1^+$)+$alpha$分量。我将$K^pi=3^+$的带头态分配给$^{10}$B在$^{14}$N的$E_x$=13.19 MeV的$ α $散射反应中观察到的$K^pi=3^+$的带头态,并表明计算的$ α $衰变宽度与实验数据一致。我讨论了$^{10}$B簇周围的$ α $簇运动,并证明$^{10}$B+$ α $簇状态包含线性链3$ α $构型的重要组成部分,其中$ α $簇在变形$^{10}$B簇周围的纵向定位。
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.
