Decay probability of oxygen and flourine clusters from 290−320122, 292−332124 and 298−326126 even-even isotopes

Abstract

Emission probability of 17−23O and 19−25F isotopes from 290−320122, 292−332124 and 298−326126 eve-even parents were studied by calculating the barrier penetrability, decay constant and decay half-lives using the Coulomb and Proximity potential Model (CPPM). The Q-values are estimated using the WS4 mass model. Clusters like 18,20O, 23,25F show the emission probability from the selected parents with a decay half-life less than the experimental upper limit of 1030 seconds. Neutron shell closure at N = 176 and 184 is identified from the plot of log10⁡T1/2 versus the neutron number of parent nuclei.
