Decay characteristics of nuclei of interest in the synthesis of Z = 120 isotopes.

The alpha and cluster decay characteristics of 2 9 9 − 3 0 2 120 isotopes in the superheavy region are investigated within the Coulomb and Proximity Potential Model (CPPM) framework. The study is significant since several attempts were made during the last one and half decades for the synthesis of Z = 120 isotopes. The alpha decay half-lives are compared with the spontaneous fission half-lives estimated using the formula of Santhosh et al.1 and identified the isotopes which are stable against spontaneous fission. Possible light cluster emission from the selected isotopes and the branching ratio (BR) are also calculated. Further, heavy cluster emission probability is also studied within the framework of the empirical formula of Prathapan and Biju (PB)2 and the Modified Balasubramaniam Formula (MBF).3 We could identify many possible heavy particle emissions with decay half-lives comparable to that of the alpha decay. Experiments can be conducted for the identification of such possible emission fragments. The alpha and cluster decay half-lives are computed using the Universal Decay Law (UDL)4 and with the Modified Universal Decay Law (MUDL)5 are also presented for comparison purposes.
