摘要

通过引入精确的核电荷半径公式和攻击频率的解析表达式，对有效液滴模型（ELDM）进行了改进。在改进的有效液滴模型（IMELDM）中，计算了跨铅区的实验簇放射性半衰期。结果表明，与 ELDM 相比，IMELDM 的精度有所提高。最后，IMELDM 预测了实验中无法获得的反式铅核的簇放射性半衰期。这些预测可能有助于在未来的实验中寻找新的候选簇放射性。

An improved effective liquid drop model for cluster radioactivity

The effective liquid drop model (ELDM) is improved by introducing an accurate nuclear charge radius formula and an analytic expression for assaulting frequency. Within the improved effective liquid drop model (IMELDM), the experimental cluster radioactivity half-lives of the trans-lead region are calculated. It is shown that the accuracy of the IMELDM is improved compared with that of the ELDM. At last, the cluster radioactivity half-lives that are experimentally unavailable for the trans-lead nuclei are predicted by the IMELDM. These predictions may be useful for searching for new candidates for cluster radioactivity in future experiments.
