Heavy particle radioactivity of superheavy element Z = 126

The concept of heavy particle radioactivity is studied using modified generalised liquid drop model (MGLDM) in the superheavy element Z = 126. The eight different proximity functions and different mass excess values were used to evaluate cluster/HPR. The logarithmic half-lives using different proximity functions and mass excess values are compared with that of experiments. The HPR of ⁶⁰Ni to ¹⁰²Ru have been studied in the superheavy region ${}_{306}126$ to ${}_{326}126$. The HPR half-lives has been compared with the different decay modes such as α-decay, β-decay and spontaneous fission. 9 HPR emitters, 4 α emitters, 1 ${\beta }^{+}$ emitter and 7 spontaneous fission nuclei were identified in the superheavy nuclei ${}_{306-314}126$, ${}_{315-318}126$, ${}_{319}126$ and ${}_{320-326}126$ respectively.
