Theoretical predictions for the decay chain of the nuclei Og293,295–297

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)Og.
