摘要: Abstract The feasibility for the alpha decay and heavy particle from even–even superheavy (SH) nuclei with Z = 116 – 124 has been studied within Coulomb proximity potential model (CPPM). Our predicted half lives agree well values evaluated using Universal formula cluster (UNIV) of Poenaru et al., Decay Law (UDL) Qi Scaling Horoi al. spontaneous fission corresponding parents have also semi-empirical Santhosh Within our model, we formation probability various clusters maximum is found accompanying 298114. In plots log 10 ( T 1 / 2 ) against neutron number daughter in decay, life to be minimum leading 298114 114 , N 184 ).
