The preformation probability of clusters in heavy nuclei is studied by comparing different formula predictions with experimentally extracted values. It is found that most formulae overpredict the preformation probabilities, except for one formula. Four new empirical formulae are proposed and shown to be in good agreement with predictions from different theoretical models.
Cluster preformation probability in heavy nuclei is studied using the empirical formula of Ni and Zhou [Ren. Phys. Rev. C 82 (2010) 24311]. Dong et al. [Eur. Phys. J. A 41 (2009) 197-204], and four new formulae of Santhosh et al. [Indian J. Phys. 95 (2021) 121]. The predictions of these formulae are then compared to the preformation probabilities extracted from the experimental decay half-lives using the generalized liquid drop model (GLDM), density-dependent cluster model (DDCM), and unified fission model (UFM). It has been found that except for the isospin-dependent formula of Santhosh et al., all other formulae predict much larger preformation probability than the experimentally extracted values. Further, we propose four new empirical formulae for the cluster preformation probability in heavy nuclei, and the predictions are compared to the experimentally extracted values using different theoretical models. It is found that the predictions of all the four proposed formulae are in good agreement with the predictions of various theoretical models.
