Theoretical predictions for the decay chain of the nuclei ${}^{293,295–297}\mathrm{Og}$

The $\alpha$-decay half-lives of recently synthesized superheavy nuclei (SHN) are investigated by employing a generalized liquid drop model (GLDM) and Royer's analytical formula. The excellent agreement with the experimental data indicates the GLDM and the analytical formula are useful tools to investigate $\alpha$-decay half-lives. The competition between $\alpha$ decay and spontaneous fission is analyzed in detail and $\alpha$-decay half-lives and decay modes are predicted for the unknown nuclei ${}^{293,295–297}\mathrm{Og}$.
