We report on new γ-ray spectroscopy results from β decays of In99 and Sn101. 30 new γ rays were observed following the β decay of In99, and inconsistencies in the literature with respect to the γ rays following the β decay of Sn101 were addressed with two confirmed cases and two new transitions. The experimental γ-ray energies, intensities, and coincidence relationships are discussed with shell model calculations, where theoretical β-decay branching ratios from the parent nuclei and γ-ray cascades of excited states from the daughter nuclei were combined to generate hypothetical βγ spectra and βγγ coincidence matrices. The most intense β-delayed γ-ray branches in both Cd99 and In101 were well reproduced with this approach, and several γ rays were assigned to new excited states based on their good agreement with shell model predictions.

来自 In99 和 Sn101 的 β 衰变的 Cd99 和 In101 的光谱

我们报告了来自 In99 和 Sn101 的 β 衰变的新 γ 射线光谱结果。在 In99 的 β 衰变之后观察到了 30 条新的 γ 射线，并且文献中关于 Sn101 β 衰变之后的 γ 射线的不一致通过两个确认的案例和两个新的跃迁来解决。通过壳模型计算讨论了实验 γ 射线能量、强度和重合关系，其中将来自母核的理论 β-衰变分支比和来自子核的激发态的 γ 射线级联组合生成假设的 βγ 光谱和βγγ 重合矩阵。用这种方法很好地再现了 Cd99 和 In101 中最强烈的 β 延迟 γ 射线分支，并且根据它们与壳模型预测的良好一致性，一些 γ 射线被分配到新的激发态。
