摘要
在这项研究中,根据所提出的变形伽莫样模型,对变形质子发射器的质子发射半衰期进行了研究,在该模型中,库仑势中包含了变形效应。质子发射器的实验半衰期可在 3.45 倍的范围内重现。为了进行比较,还介绍了通用衰变定律和新的盖革-努塔尔定律的结果。此外,还分析了 117La、121Pr、135Tb 和 141Ho 的半衰期与角动量 l 的相关性,并提出了相应的可能 l 值:l = 3、3、4、4。
Theoretical calculations of proton emission half-lives based on a deformed Gamow-like model* * Supported in part by the National Natural Science Foundation of China (12175100, 11975132), the Construct Program of the Key Discipline in Hunan Province, the Research Foundation of Education Bureau of Hunan Province, China (21B0402, 18A237), the Natural Science Foundation of Hunan Province, China (2018JJ2321), the Innovation Group of Nuclear and Particle Physics in USC, the Shandong Province Natural Science Foundation, China (ZR2022JQ04), the Hunan Provincial Innovation Foundation For Postgraduate (CX20220993), and the Opening Project of Cooperative Innovation Center for Nuclear Fuel Cycle Technology and Equipment, University of South China (2019KFZ10).
In this study, proton emission half-lives were investigated for deformed proton emitters with based on the presented deformed Gamow-like model, where the deformation effect was included in the Coulomb potential. The experimental half-lives of proton emitters can be reproduced within a factor of 3.45. For comparison, the results from the universal decay law and the new Geiger-Nuttall law are also presented. Furthermore, the relevance of the half-lives to the angular momentum l for 117La, 121Pr, 135Tb, and 141Ho were analyzed, and the corresponding possible values of l were proposed: l = 3, 3, 4, 4.
