关于 93 Mo中21/2 + 晕阱的来源(英文)

本研究通过壳模型计算研究了N=51的同中子素91Zr、93Mo和95Ru中高自旋晕态21/2+的同核异能态现象。计算发现，低角动量的p1/2轨道上的质子是仅在93Mo中存在21/2+晕阱的主要原因。同时，本工作还研究了N=52的同中子素92Zr、94Mo和96Ru中101+-121+能级结构的系统性，发现94Mo中的101+-121+能级间隙相对最小，考虑到与93Mo的17/21+-21/21+能级相似的组态，这一结果为93Mo中出现21/2+晕阱提供了补充性的论证。 Isomerism of the high-spin yrast 21/2+ states of the N=51 isotones 91Zr, 93Mo and 95Ru has been investigated using the shell model calculations. It is found that the low-j πp1/2 is responsible for the only yrast trap in 93Mo. In addition, the relatively smaller 101+-121+ level spacing in 94Mo has been found by investigating the systematics of the 101+-121+ level structures in the N=52 isotones 92Zr, 94Mo and 96Ru. This result provides a supplementary argument to the origin of the 21/2+ yrast trap in 93Mo from the viewpoint of the similarity between the configurations of 101+-121+ states in 94Mo and those of 17/21+-21/21+ states in 93Mo.
