Abstract The extremely neutron-deficient isotopes 177,179Au were studied by means of in-beam γ-ray spectroscopy. Specific tagging techniques, α-decay tagging in 177Au and isomer tagging in 179Au, were used for these studies. Feeding of positive-parity, nearly spherical states, which are associated with 2 d 3 / 2 and 3 s 1 / 2 proton-hole configurations, from the 1 i 13 / 2 proton-intruder configuration was observed in 177Au. Such a decay path has no precedent in odd-Au isotopes and it is explained by the effect of mixing of wave functions of the initial state.

来自 177Au 中高自旋入侵者状态的低自旋正奇偶带的种群：二态混合效应

摘要 利用射内γ射线能谱研究了极缺中子同位素177,179Au。这些研究使用了特定的标记技术，即 177Au 中的 α-衰变标记和 179Au 中的异构体标记。在 177Au 中观察到来自 1 i 13 / 2 质子入侵者构型的正奇偶近球形状态的馈送，这些状态与 2 d 3 / 2 和 3 s 1 / 2 质子孔构型相关。这种衰变路径在奇金同位素中没有先例，它可以通过初始状态波函数的混合效应来解释。
