Beta-decay half-lives for [beta][sup +]/EC (electron capture) decay for neutron-deficient nuclei with atomic numbers Z = 10--108 have been calculated up to the proton drip line. For this purpose a proton-neutron quasiparticle random-phase approximation model (pn-QRPA) has been used. Both particle-hole and particle-particle residual interactions are taken into account. The calculated half-lives are in good agreement with experimental data, indicating the applicability of the model to the prediction of half-lives of unknown isotopes. The results of the present calculation are also compared to earlier theoretical work. It is shown that the pn-QRPA leads to considerable improvement over gross theory calculations. 81 refs., 16 figs., 2 tabs.
