我们报告的低激发态的中子富同位素测量的一部分，在RIKEN放射性同位素束工厂的“壳进化和搜索两个加能量在RIBF”（SEASTAR）运动的射线光谱。观察到激发的yrast和非yrast状态，并且半衰期提取了vigeant 4模拟。该州的候选人已经确定。对于，即时SEASTAR数据与延迟光谱数据相结合，用EURICA阵列测量，以观察在195.5（3）keV能级上的已知异构体的顶部的跃迁。将新的实验结果与五维集体汉密尔顿（5DCH）和映射相互作用玻色子模型（IBM）计算（均使用Gogny D1 M相互作用）进行比较，可能表明扁长-扁长形状已经共存。
We report on-ray spectroscopy of low-lying excited states in the neutron-richisotopes measured as part of the “Shell Evolution And Search for Two-plus energies At RIBF” (SEASTAR) campaign at the RIKEN Radioactive Isotope Beam Factory. Excited yrast and non-yrast states were observed, and half-lives extracted viageant4simulations. Incandidates for thestate were identified. For, the prompt SEASTAR data were combined with delayed spectroscopic data measured with the EURICA array to observe transitions on top of the knownisomer at a level energy of 195.5(3) keV. The comparison of the new experimental results with five-dimensional collective Hamiltonian (5DCH) and mapped interacting boson model (IBM) calculations, both using the Gogny D1M interaction, could suggest oblate-prolate shape coexistence already in.
