用美国国家超导回旋加速器实验室的NaI（Tl）（SuN）求和探测器研究了~（60）Co的衰变。每个同位素的衰变馈电强度分布是通过测量与发射的电子重合的射线来提取的。每一个核的预测进行了比较，准粒子随机相位近似（QRPA）模型，这是常用的计算衰变性质的天体物理应用。主要目标是提供与天体物理过程有关的丰中子核的实验数据。此外，提取的衰变馈电强度分布可以导致更好地了解周围快速结构变化区域的核结构。最后，实验数据对核反应堆的反中微子研究也有意义.
Thedecays ofwere studied with the Summing NaI(Tl) (SuN) detector at the National Superconducting Cyclotron Laboratory. The-decay feeding intensity distributionfor each isotope was extracted by measuringrays in coincidence with an emitted electron. Thewas extracted via the total absorption spectroscopy technique. Thefor each nucleus was compared to predictions made by the quasiparticle random-phase approximation (QRPA) model which is commonly used to calculate-decay properties for astrophysical applications. The main goal was to provide experimental data for neutron-rich nuclei, relevant to the astrophysicalprocess. In addition, the extracted-decay feeding intensity distributions can lead to a better understanding of nuclear structure in a region of rapid structure changes around. Finally, experimental data forare also of interest to antineutrino studies of nuclear reactors.
