An improved semi-empirical formula including.isospin effects for α decay and cluster radioactivity halflives.is proposed based on the WKB barrier penetrability..Compared with the original formula, a nuclear potential with.an isospin related Woods-Saxon form is considered in total.potential energy of the radioactive system in the presentwork..It is found that the inclusion of the isospin correlation term.improves the agreement of the theoretical results of half-lives.and the experimental data. Moreover, a statistical analysis is.performed for the experimental detected cluster radioactivity..Predictions for α decay half-lives together with the branching.ratio between the α decay and cluster emissions are proposed.for some unknown superheavy nuclei with Z = 118, 120,.122, and 124 using this improved semi-empirical formula.
