论文摘要
Chiara等人最近的论文。提供了通过电子捕获（NEEC）进行核激发的第一个实验证据，从而做出了长期的理论预测。 NEEC被推断为将钼93中异构体激发到更高状态的主要通道，从而迅速释放全异构体能量（异构体耗竭）。推导的大型激发概率$ p_ {exc} $ = 0.010（3）对于这种机制，暗示着对恒星环境中核的存活的强烈影响。但是，根据以下理论工作约9个数量级，激发概率远高于估计的neec概率$ p_ {neec} $。然而，据报道的$ p_ {exc} $预计是由于其他未知机制引起的，导致异构体耗竭，预计该机制将开放核能的存储和释放的新时代。在这里，我们报告了报告的实验结果的分析，表明观察到的异构体耗竭因污染而被显着高估。
The recent paper by Chiara et al. provided the first experimental evidence of nuclear excitation by electron capture (NEEC), responding a long-standing theoretical prediction. NEEC was inferred to be the main channel to excite an isomer in Molybdenum-93 to a higher state, leading to a rapid release of full isomer energy (isomer depletion). The deduced large excitation probability $P_{exc}$=0.010(3) for this mechanism implied strong influence on the survival of nuclei in stellar environments. However, the excitation probability is much higher than the estimated NEEC probability $P_{NEEC}$ according to a following theoretical work by approximately 9 orders of magnitude. Nevertheless, the reported $P_{exc}$ is predicted to be due to other unknown mechanism causing isomer depletion, which is expected to open up a new era of the storage and release of nuclear energy. Here we report an analysis of the reported experimental results, showing that the observed isomer depletion is significantly overestimated due to the contamination.
