Heavy particle radioactivity of superheavy element Z = 126

Abstract

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 126306 to 126326. 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 β+ emitter and 7 spontaneous fission nuclei were identified in the superheavy nuclei 126306−314, 126315−318, 126319 and 126320−326 respectively.
