关于^(93)Mo中21/2^+晕阱的来源（英文）

On the Origin of 21/2^+Yrast Trap in ^(93)Mo

本研究通过壳模型计算研究了N=51的同中子素^(91)Zr、^(93)Mo和^(95)Ru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p_(1/2)轨道上的质子是仅在^(93)Mo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^(92)Zr、^(94)Mo和^(96)Ru中10_1^+-12_1^+能级结构的系统性,发现^(94)Mo中的10_1^+-12_1^+能级间隙相对最小,考虑到与^(93)Mo的17/2_1^+-21/2_1^+能级相似的组态,这一结果为^(93)Mo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 （91）Zr, （93）Mo and （95）Ru 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 （93）Mo. In addition, the relatively smaller 10_1＋-12_1＋ level spacing in （94）Mo has been found by investigating the systematics of the 10_1＋-12_1＋ level structures in the N = 52 isotones （92）Zr,（94）Mo and （96）Ru.This result provides a supplementary argument to the origin of the 21/2＋ yrast trap in （93）Mo from the viewpoint of the similarity between the configurations of 10_1＋-12_1＋ states in （94）Mo and those of 17/2＋1-21/2_1＋ states in （93）Mo.
