中文摘要：

再次研究了丰中子核^91Y的高自旋能级结构通过^82Se（^13C, p3n）^91Y反应。新建立的包含几条关键能级的能级纲图澄清了以前研究中的几点不确定的地方。这几条能级具有Z=38和N=56子闭壳打破的特征,这涉及到张量力和自旋-同位旋依赖的中心力。

英文摘要：

High-spin level structure of the neutron-rich nucleus ^91Y has been reinvestigated via the ^82Se（^13C, p3n）^91Y reaction. A newly constructed level scheme including several key levels clari？es the uncertainties in the earlier studies. These levels are characterized by the breaking of the Z = 38 and N = 56 subshell closures, which involves in tensor force and the spin-isospin dependent central force.
