摘要
The alpha-decay chains of the isotopes (265-279)Mt are predicted by comparing the a half-lives calculated within the Coulomb and proximity potential model for deformed nuclei of Santhosh et al. [Nucl. Phys. A 850, 34 (2011)] with the spontaneous fission half-lives using the shell-effect-dependent formula of Santhosh and Nithya [Phys. Rev. C 94, 054621 (2016)]. alpha half-lives also are calculated using different theoretical formalisms for comparison. The predicted half-lives and decay modes match well with the experimental results. The use of four different mass tables for calculating the alpha-decay energies indicates that the mass table of Wang et al. [Chin. Phys. C 41, 030003 (2017)], which is based on the AME2016 atomic mass evaluation, is in better agreement with experimental results. The paper predicts long alpha chains from (265,267-269,271-273)Mt with half-lives within experimental limits. The isotopes (274-276,278)Mt exhibit 2 alpha chains followed by spontaneous fission. The 2 alpha chain of (266)Mt and the 4 alpha chain of (270)Mt end with electron capture. The isotopes (277,279)Mt decay via spontaneous fission. We hope that the paper will open up new areas in this field.
