Abstract

The stability of superheavy nuclei is studied through different decay modes. Heavy-particle radioactivity with emitted clusters with \({{Z}_{e}} > 28\) allow to form daughter doubly magic nuclei \(^{{208}}\)Pb. We have investigated the heavy particle radioactivity (HPR) of superheavy element Z = 122 with mass number range \(294 \leqslant A \leqslant 340\) using the Coulomb and proximity potential model (CPPM) and modified liquid drop model (MGLDM). Present work is validated by comparing with experiments. From the study of competition between different decay modes, it is observed that isotopes of SHN with \(Z\) = 122 shows HPR in a mass number range \(294 \leqslant A \leqslant 305\). Among the identified HPR region, the isotopes of SHN Z = 122 with mass number range \(294 \leqslant A \leqslant 300\) may undergoes \(^{{86}}\)Kr emission. The isotopes of SHN 122 with mass number range \(301 \leqslant A \leqslant 305\) undergoes HPR by the emission of \(^{{94}}\)Zr. This may be due to shell effect.
