摘要：

在结合双折叠势的$α$ -团簇模型框架下，研究了重$N = Z$核$^{88}$ Ru中的Yrast带.它被发现，在$^{88}$ Ru的yrast带的激发能可以很好地描述内的$α$ -集群的方法，使用一个平滑和温和的$L$ -依赖调整的潜在强度。这一结果类似于在具有（魔核$\otimes$ $α$）结构的原子核中建立良好的$α$团簇态。相反，在相邻的$N \ne Z$核的yrast带偏离这种典型的$α$ -集群行为。最后，$α$ -簇模型预测约10 Weisskopf单位的带内跃迁之间的低躺态之间的yrast带的$^{88}$ Ru的减少的过渡强度。

英文摘要：

The yrast band in the heavy $N = Z$ nucleus $^{88}$Ru is studied in the framework of the $α$-cluster model in combination with double-folding potentials. It is found that the excitation energies of the yrast band in $^{88}$Ru can be nicely described within the $α$-cluster approach using a smooth and mildly $L$-dependent adjustment of the potential strength. This result is similar to well-established $α$-cluster states in nuclei with a (magic core $\otimes$ $α$) structure. Contrary, the yrast bands in neighboring $N \ne Z$ nuclei deviate from such a typical $α$-cluster behavior. Finally, the $α$-cluster model predicts reduced transition strengths of about 10 Weisskopf units for intraband transitions between low-lying states in the yrast band of $^{88}$Ru.
