Abstract The evaluated spectroscopic data are presented for 12 known nuclides with A=217 (Tl, Pb, Bi, Po, At, Rn, Fr, Ra, Ac, Th, Pa, U). For 217 Tl, 217 Pb, 217 Pa, and 217 U nuclei, only information on the ground state is available. Levels in 217 Bi are known only from isomer decay following fragmentation reaction and those in 217 At and 217 Rn only from the α decay of 221 Fr and 221 Ra, respectively. High spin levels in 217 Ra are mainly from 1987SuZY and 2011MuZZ which are a lab report and thesis, respectively. Due to differences between these studies, further experimental study is needed to firmly establish the level scheme. This evaluation was carried out as part of a joint IAEA-ICTP workshop for Nuclear Structure and Decay Data, organized and hosted by the IAEA, Vienna and ICTP, Trieste, Aug 22 to Sept 2 2016. The evaluation work was coordinated by E.A. McCutchan (BNL). This work supersedes the previous previous A=217 evaluation (2003Ak06) by Y.A. Akovali.

A=217 的核数据表

摘要 评估了 12 种已知核素的光谱数据，其中 A=217（Tl、Pb、Bi、Po、At、Rn、Fr、Ra、Ac、Th、Pa、U）。对于 217 Tl、217 Pb、217 Pa 和 217 U 核，只有基态信息可用。217 Bi 中的水平仅从碎裂反应后的异构体衰变中得知，而 217 At 和 217 Rn 中的水平仅分别来自 221 Fr 和 221 Ra 的 α 衰变。217 Ra 的高自旋能级主要来自 1987SuZY 和 2011MuZZ，分别是实验室报告和论文。由于这些研究之间存在差异，需要进一步的实验研究以牢固建立水平方案。该评价是作为 IAEA-ICTP 核结构和衰变数据联合研讨会的一部分进行的，该研讨会由 IAEA、维也纳和 ICTP 于 2016 年 8 月 22 日至 9 月 2 日在的里雅斯特组织和主办。评估工作由 EA McCutchan (BNL) 协调。这项工作取代了之前由 YA Akovali 进行的 A=217 评估 (2003Ak06)。
