Description
Summary:The cluster decay (CD) half-lives (HL) are investigated using the Coulomb and proximity potential model (CPPM) and modified generalized liquid drop model (MGLDM). The proximity functions Prox-13[European Physical Journal A 49, 1 (2013)], MP-77 [Annals of Physics 132, 53 (1981), Pramana 76, 921 (2011)], Prox-77 [Annals of Physics 105, 427 (1977)], MP-81 [Annals of Physics 132, 53 (1981)], Ng-80[Nuclear Physics A 348, 140 (1980)] and DP-00 [Physics Letters B 526, 315 (2002)] were used to evaluate CD half-lives. The mass excess FRLDM will more precisely reproduce experimental decay energy. The computed CD half-lives using the Prox-13 function can more closely reflect experimental data. The decay half-lives of odd superheavy nuclei (SHN) within the atomic number (Z) range 105 ≤ Z ≤ 125 for cluster emission from helium to calcium are expected. The entrance channel parameters on the logarithmic half-lives (LHL) provide insight into future cluster radioactivity (CR) experiments.
