用统一裂变模型（UFM）研究了重核的各种团簇放射性。利用UFM结合实验半衰期提取了团簇预形成因子，并详细讨论了团簇预形成几率与粒子预形成几率的关系。此外，还在统计物理的框架下研究了团簇的形成概率。对团簇发射半衰期的一些有用的预测提供了未来的实验。
Various cluster radioactivities of heavy nuclei have been investigated by using the unified fission model (UFM). The cluster preformation factors have been extracted by employing the UFM connected with the experimental half-lives, and the relationship of preformation probability between the cluster and-particle has been discussed in detail. In addition, the cluster preformation probability has been studied in the framework of statistical physics. Some useful predictions on the cluster emission half-lives are provided for future experiments.
