通过使用 [sup 160]Gd([sup 34]S、4n 和 5n) 反应以及十二个康普顿抑制 Ge 探测器阵列，[sup 189]Hg 和 [sup 190]Hg 原子核的能级结构已从早期研究中得到了相当大的扩展。 [sup 189]Hg 中描绘了八个能带结构，[sup 190]Hg 中描绘了十个能带结构。大多数能带可以在曲柄壳模型计算的框架内理解，假设扁圆形集体形状和提出的特定准粒子配置。还有一些证据表明三轴性的出现。在这两种核能级结构中，看似非集体的特征都在能带终止图中得到解释。 ((原))
The level structures of the [sup 189]Hg and [sup 190]Hg nuclei have been extended considerably from earlier studies by using the [sup 160]Gd([sup 34]S, 4n and 5n) reactions in conjunction with an array of twelve Compton suppressed Ge detectors. Eight band structures have been delineated in [sup 189]Hg and ten in [sup 190]Hg. Most bands can be understood within the framework of cranked shell model calculations assuming an oblate collective shape and specific quasiparticle configurations are proposed. There is also some evidence for the onset of triaxiality. In both nuclei level structures which appear to be non-collective in character are interpreted in a band termination picture. ((orig.))
