英文摘要The competition between alpha and beta decays is investigated for neutron-deficient Pa, U, Np, and Pu isotopes. beta(+)/electron-capture (EC) decay rates are calculated within the deformed quasiparticle random-phase approximation with realistic nucleon-nucleon (NN) interactions. Contributions from allowed Gamow-Teller and Fermi transitions as well as first-forbidden transitions are considered. alpha-decay calculations are performed within the generalized density-dependent cluster model. Effects of differences between neutron and proton distributions and nuclear deformation are taken into account. In the calculations, Reid-93 NN interactions are used for beta' /EC decays, while Michigan three-range Yukawa effective interactions, based on the G-matrix elements of Reid NN potentials, are used for a decay. The calculated beta-decay half-lives show good agreement with the experimental data over a range of magnitude from 10(2) to 10(5) s. The resulting total half-lives including alpha and beta contributions are found to be in good agreement with the experimental data, together with the alpha/beta-decay branching ratios.
