摘要: 针对目前70个重要短寿命核素的γ射线全吸收(TAGS)数据, 提出新的评价方案和标准, 结合直接测量数据进行系统性比对评价, 并基于Gross理论对β衰变进行理论研究. 研究结果表明, 奇核子导致的高能级密度及跃迁几率的描述不准确是目前影响衰变热物理描述的主要因素.

关键词: 衰变热, 裂变产物, 数据评价, Gross理论

Abstract: We proposed a new evaluation scheme and standard for the total absorption Gamma ray spectroscopy data of the 70 important short-lived nuclei, combined with direct measurement data for systematic comparison and evaluation, and conducted theoretical research on β decay based on the Gross theory. The research results show the inaccurate description of high-energy density and transition probability caused by odd nucleon is currently the main factor affecting the physics description of decay heat.

Key words: decay heat, fission product, data evaluation, Gross theory
