摘要：

The beta decay rate of the 1+ ground state of Tc-100 to the ground and excited states of Mo-100 and Ru-100 has been calculated using a combination of the charge-conserving and charge-nonconserving modes of the quasiparticle random phase approximation theory. These results, as well as the calculated E2 decay properties of Mo-100 and Ru-100, are compared with data. In addition, the two-neutrino double beta decay rates of Mo-100 to the ground state and excited states of Ru-100 are evaluated and analyzed using available experimental data. For completeness, the neutrinoless double beta decay rate of Mo-100 is calculated and used to extract the value of the effective neutrino mass and the parameters of a general weak-interaction Hamiltonian.
