使用高分辨率 Ge(Li) 探测器研究了 10.5 分钟 186Ta 衰变产生的伽马射线。已观测到超过 90 条伽马射线。之前报道为单线的几个光峰被发现是接近的双峰。这项研究的结果已与已发表的 γ-γ 符合数据和最近的 (d,d′) 反应工作相关联，并构建了 186Ta 的衰变方案。该方案在 186W 中包含 23 个激发态之间超过 85 个跃迁。 1661 keV 的能级已经根据尼尔森轨道 Ωπ[NnzΛ] = 7/2+[404] 和 1/2+[411] 产生的二质子准粒子态进行了讨论。提取了几个转移概率，并将其与其他最近的实验数据、Kumar 和 Baranger 的计算以及各种唯象模型的预测进行了比较。
Gamma rays from the decay of 10.5 min 186Ta have been studied using high resolution Ge(Li) detectors. More than 90 gamma rays have been observed. Several photo-peaks previously reported as single lines were found to be close doublets. The results of this study have been correlated with the published γ–γ coincidence data and the recent (d,d′) reaction work and a decay scheme for 186Ta has been constructed. The scheme incorporates more than 85 transitions among 23 excited states in 186W. The level at 1661 keV has been discussed in terms of a two-proton quasi-particle state arising from the Nilsson orbitals Ωπ[NnzΛ] = 7/2+[404] and 1/2+[411]. Several transition probabilities have been extracted and compared with other recent experimental data and with the calculations of Kumar and Baranger as well as with the predictions of various phenomenological models.
