In this paper, the heavy cluster half-lives were calculated using the Wentzel–Kramers–Brillouin (WKB) method. First, we have considered the cluster and daughter nuclei as spherical and the half-lives have been obtained. Then, we have assumed two nuclei as deformed ones and calculations have been performed once again. Deformations of the emitted cluster and daughter nucleus have been presented in terms of elongation and neck thickness parameters. We investigated the influence of elongation and neck thickness parameters on cluster decay half-lives. Our results show that half-lives are affected by these parameters and obtained results for deformed nuclei are in better agreement with experimental data.
