摘要
利用１７７Ｈｆ（１９Ｆ，９ｎ）１８７Ｔ１反应和在线同位素分离法，对１８７Ａｕ低激发态能级结构进行了γ-γ符合与γ-ｅ符合的测量分析，束流能量为１７５ＭｅＶ，发现了多条新的跃迁，测量了内转换系数，扩展了１８７Ａｕ的能级图．对１８７Ａｕ低激发态下的集体带结构、单质子与不同偶-偶核芯的耦合特性进行了讨论．
The low spin level structure of 187Au has been studied. by isotopically separated method. The reaction was 177HF(19F,9n)187T1 with beam energy 175MeV. The level scheme of 187Au was expanded and enhanced through analyzing γ-γ and γ-e coincidence data. The collective band structures and the coupling single proton with different even-eved cores were discussed.
