摘要

我们改进了Poenaru等人（Phys Rev C 74: 014312, 2006）的SemFIS公式，包括角动量的影响，并系统地研究了184−224Bi （Z = 83）基态和异构体态的α衰变半衰期。我们进一步完善了Akrawy等人（核物理学报1021:122419,2022）改进的SemFIS模型，消除了其在再现铋同位素实验数据方面的缺陷，改进的SemFIS模型在预测α衰变半衰期方面显示出更高的准确性。同时，利用改进的广义液滴模型（MGLDM）预测了α衰变半衰期，该模型具有新的预成型参数和其他经验公式。在所有模型中，新盖格-纳托尔定律的标准差最小。我们希望我们的预测将有助于这一领域的进一步实验研究。

Comparative study on α-decay of ground and isomeric states of Bi isotopes using improved semi-empirical relationship & modified GLDM

We have improved the SemFIS formula by Poenaru et al. (Phys Rev C 74: 014312, 2006), including the effect of angular momentum and a systematic study on alpha decay half-life of ground and isomeric states of ^184−224Bi (Z = 83) is investigated. We further refined the modified SemFIS by Akrawy et al. (Nucl Phys A 1021: 122419, 2022) eliminates its drawbacks in reproducing experimental data on bismuth isotopes, and the improved SemFIS models show higher accuracy in predicting alpha decay half-life. Also, alpha decay half-life is predicted using the Modified Generalized Liquid Drop Model (MGLDM), its improved version with new preformation parameters and other empirical formulas. Among all models, the New Geiger-Nuttall law demonstrates the lowest standard deviation. We hope our predictions will contribute to further experimental inquiries in this domain.
