CERN-Isolde设施的Isolde衰变站发现了一种新的衰变状态。在壳层模型计算中，根据能级的-衰变馈送模式，建议对这种状态进行较好的赋值。这个国家的半衰期被推断为贝敏。通过偶发事件研究了这种态的衰变引起的能级的退激，并发现了一些新的能级和跃迁。用两种不同的有效相互作用：H208和修正的Kuo-Herling粒子相互作用，对激发态进行了壳层模型计算。这两个计算都同意将新衰变状态解释为各向异性，并允许将壳模型状态暂定为文中的几个高自旋态。
A new-decaying state inhas been identified at the ISOLDE Decay Station at the CERN-ISOLDE facility. A preferredassignment was suggested for this state based on the-decay feeding pattern to levels inand shell-model calculations. The half-life of thestate was deduced to bemin. The deexcitation of the levels populated inby thedecay of this state was investigated viacoincidences and a number of new levels and transitions was identified. Shell-model calculations for excited states inandwere performed using two different effective interactions: the H208 and the modified Kuo-Herling particle interaction. Both calculations agree on the interpretation of the new-decaying state as anisomer and allow for tentative assignment of shell-model states to several high-spin states in.
