Predictions on the alpha decay chains of superheavy nuclei with Z = 121 within the range 290 ≤ A ≤ 339

A systematic study on the alpha decay half-lives of various isotopes of superheavy element (SHE) Z = 121 within the range 290 ≤ A ≤ 339 is presented for the first time using Coulomb and proximity potential model for deformed nuclei (CPPMDN). The calculated α decay half-lives of the isotopes within our formalism match well with the values computed using Viola-Seaborg systematic, Universal curve of Poenaru et al., and the analytical formula of Royer. In our study by comparing the α decay half-lives with the spontaneous fission half-lives, we have predicted 2α chain from 309,311,312121, 3α chain from 310121 and 1α chain from 313,314121. Clearly our study shows that the isotopes of SHE Z = 121 within the mass range 309 ≤ A ≤ 314 will survive fission and can be synthesized and detected in the laboratory via alpha decay. We hope that our predictions will provide a new guide to future experiments.
