本文给出了衰变进给强度分布和Gamow-Teller 转变强度分布。这些量是在国家超导回旋加速器实验室使用总吸收光谱技术和 Summing NaI(Tl) 探测器进行测量的。这些测量为用于预测远离天体物理应用稳定性的衰变特性的理论模型提供了敏感的约束。具体而言，对于天体物理过程，大多数涉及的原子核是现有设施无法接近的，核输入主要由理论提供。目前的工作报告了该区域的两种富中子镍同位素，预计弱过程与恒星核合成有关。将实验结果与两个理论模型（即壳模型和准粒子随机相近似）进行比较，以帮助进一步完善理论计算并有助于未来的过程研究。
This paper presents the-decay feeding intensity distribution and Gamow-Teller transition strength distribution of. These quantities were measured using the technique of total absorption spectroscopy at the National Superconducting Cyclotron Laboratory with the Summing NaI(Tl) detector. These measurements provide sensitive constraints to theoretical models used to predict-decay properties far from stability for astrophysical applications. Specifically, for the astrophysicalprocess, the majority of the involved nuclei are not accessible by current facilities, and the nuclear input is mainly provided by theory. The present work reports on two neutron-rich nickel isotopes in the region where the weakprocess is expected to be relevant in stellar nucleosynthesis. The experimental results are compared to two theoretical models, namely the shell model and the quasiparticle random-phase approximation, to help further refine theoretical calculations and aid in future-process studies.
