Probable chances of radioactive decays from superheavy nuclei 290-304120 within a modified generalized liquid drop model with a Q-value-dependent preformation factor

All possible chances of heavy-cluster emissions are predicted for even-even isotopes of (290-304)120 using the modified generalized liquid drop model with a Q-value-dependent preformation factor. We have considered only those cluster emissions with half-life below the measurable limits. We have also estimated the probable heavy cluster emitted from each isotope of (290-304)120 with half-life comparable to alpha-decay half-life and the most probable cluster emission with the least half-life among all cluster-daughter combinations possible, and the predicted decays have either magic number of protons or neutrons or near to it. The highest and second highest a-decay half-life from (290-304)120 corresponds to (298)120 and (304)120, both isotopes with magic or semimagic numbers. Thus, the role of the magic number in stability is highlighted through our paper. The predicted a half-lives are compared with other theoretical models and are in agreement. For the first time we explore the possibility of 2 alpha decay from the superheavy (SH) nuclei. The agreement in theoretical alpha-decay half-lives with experimental values for the isotopes in the decay chains of Z = 120 shows the predictability of the model in the SH region, and so we predict the isotopes (290,292)120 decays by 6 alpha-decay chains and even-even isotopes (294-304)120 decays by 4 alpha-decay chains. Our predictions become particularly important as the predicted half-lives are within experimentally measurable limits and can be detected in the near future.

Automated summary

This study predicts the possible chances of heavy-cluster emissions for even-even isotopes of (290-304)120 using a modified generalized liquid drop model. The results show that isotopes with magic or semimagic numbers tend to have longer a-decay half-lives. The agreement between theoretical alpha-decay half-lives and experimental values in the Z = 120 decay chains demonstrates the predictability of the model in the superheavy region. The predictions made in this study are important as they can be detected in the near future within experimentally measurable limits.
