Abstract:
In the present work, we predict the α decay half-lives of unknown even-even nuclei 296–308 120 within the two-potential approach, whose α decay energy Q α is calculated using WS3+ mass model. To reduce the deviations between the predictions and experimental data due to nuclear shell effect, the analytic formula of α decay hindrance factor is introduced to the two-potential approach, whose parameters had been extracted from even-even nuclei in the region of 82 〈 Z ≤ 126 and 152 〈 N ≤ 184 in our previous work [Deng et al ., Chin. Phys. C 42 (2018) 044102]. In addition, for comparing, we use a type of α decay general formula Universal Decay Law (UDL) and a semi-empirical formula in the superheavy nucleus (SEMFLS) to calculate the half-lives of even-even nuclei 296–308 120. The results indicate that our predicted values and the calculated values of the above two empirical formulas are mutually confirmed. Meanwhile, we systematically study α decay chains of 296–308 120 and predict the decay modes for superheavy nuclei to help to identify new superheavy isotopes.
