The half-lives of β decay and electron capture are compared with α-decay half-lives obtained from phenomenological formulas. The sensitivity of the half-lives to the unknown Q-energies is studied by comparing the results obtained from different approaches for the masses. It is shown that α-decay is always dominant in this mass region. The competition between α and β/EC decay modes is studied in seven α-decay chains starting at different isotopes of Z=118, 119, and 120.This work was supported by Ministerio de Ciencia e Innovación MCI/AEI/FEDER, UE (Spain) under Contract No. PGC2018-093636-B-I00Elsevier BVMinisterio de Ciencia, Innovación y Universidades (España)SCOAPConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2021202120212021info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/248354reponame:DIGITAL.CSIC.
