论文摘要
使用SLY4 Skyrme力的理论QRPA计算，已首次使用总吸收伽马光谱技术来首次确定$^{186} $ Hg衰减的Gamow-Teller强度分布。测得的游戏性强度分布和半衰期是通过独立于父母和女儿核中的扁平和扁平构型来描述的。实验性β强度的最佳描述是用父$^{186} $ HG和女儿$^{186} $ au获得的主要块状组件。该方法还使我们能够确定母体状态中植物成分的上限。分析的复杂性需要开发一种新方法，以分析X射线门控总吸收光谱。
The Gamow-Teller strength distribution of the decay of $^{186}$Hg into $^{186}$Au has been determined for the first time using the total absorption gamma spectroscopy technique and has been compared with theoretical QRPA calculations using the SLy4 Skyrme force. The measured Gamow-Teller strength distribution and the half-life are described by mixing oblate and prolate configurations independently in the parent and daughter nuclei. The best description of the experimental beta strength is obtained with dominantly prolate components for both parent $^{186}$Hg and daughter $^{186}$Au. The approach also allowed us to determine an upper limit of the oblate component in the parent state. The complexity of the analysis required the development of a new approach in the analysis of the X-ray gated total absorption spectrum.
