EVALUATION OF 40K NUCLEAR DECAY DATA, VIA MODEL NUCLEAR PROJECTILES

The nuclear decay data of40K have been evaluated in this study via model nuclear projectiles. The reactants were carefully identified with the aid of KarlsruherNuklidkarte with the target nucleus in order to obtain the residual nuclide (40K ) and liberating the ejectile particle or in multiple. The liberation of 40K in the study via all the reactions channels was based on production routes initiated and balanced to give 45Cr (n, 2β + Pn)40K ,46Mn (n, 2n Li Pβ+)40K , 37Ar (α, P )40K ,42Sc (β-, 2n)40K , and 49Ni(2β-, 2α 2β+)40K . Multiple tasks were performed with; EXFOR, Nucleonica, KAERI, CSISRS, Nudat especially compatibility of the decay data with their specifications in order to achieve theoretical cross section calculation data. The calculated Q-Values and Threshold energies were determined from the nuclear reactions and subsequently the excitation functions. Further empirical approach is encouraged in bids to realize more potential pathways of decay data of40K . Finally, the experimental study of this result is expected to unveil more insights. Their potential outcome this study is expected to address human quests in nuclear medicine, nuclear energy and nuclear arms against  insecurity and military aggressions.

本研究采用模型核入射粒子（model nuclear projectiles）对40K（钾40）的核衰变数据开展评价工作。研究借助卡尔斯鲁厄核素图（Karlsruher Nuklidkarte）对靶核相关反应物进行精准甄别，以获得余核40K并释放出射粒子（或多组出射粒子）。本研究中通过所有反应道生成40K的过程，均基于经过验证与平衡的生成路径，具体包括：45Cr(n,2β+Pn)40K、46Mn(n,2nLiPβ+)40K、37Ar(α,P)40K、42Sc(β-,2n)40K以及49Ni(2β-,2α2β+)40K。本研究依托国际核反应截面数据库（EXFOR）、Nucleonica、韩国原子能研究院（KAERI）、CSISRS、Nudat等数据库开展多项工作，重点验证衰变数据与各数据库规范的兼容性，以获取理论截面计算所需的相关数据。本研究从核反应出发计算得到Q值（Q-Value）与阈能（Threshold energy），随后进一步推导得到激发函数（excitation function）。本研究呼吁采用更多经验方法，以挖掘40K衰变数据更多潜在的生成路径。最后，本研究的实验结果有望为该领域提供更多新认知。本研究的潜在成果有望满足人类在核医学、核能以及用于抵御不安全局势与军事侵略的核军备领域的相关诉求。
