The centrifugal potential has a significant impact on the total potential of the decay system. But it is always ignored in many models and semi-empirical formulas. In this work, an improved semi-empirical formula including the contribution of centrifugal potential for decay half-lives has been proposed based on the Wentzel–Kramers–Brillouin (WKB) barrier penetration. Compared to other semi-classical formulas, the formula in this work has the smallest standard deviation. By using this formula, the decay half-lives of even–even and odd-A nuclei with atomic numbers Z = 117, 118, 119, and 120 are predicted. The calculated decay half-lives of 293Ts and 294Og exhibit good agreement with experimental measurements. The characteristics of predicted decay energy and half-lives indicate that N = 184 is the next neutron magic number after N = 126. Finally, the competition between decay and spontaneous fission is investigated. The decay modes for isotopes 289–317Ts, 290–318Og, 291–319119, and 292–320120 are also shown.
