Abstract In the present work, we predict the α decay half-lives of unknown even-even nuclei296–308120 within the two-potential approach, whose α decay energy Qα 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., Ch...
