Microscopic Predictions of β+/EC-Decay Half-Lives

摘要: Beta-decay half-lives for β+/EC (electron capture) decay 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 used. Both particle-hole and particle-particle residual interactions are taken into account. The in good agreement experimental data, indicating applicability of prediction unknown isotopes. results present calculation also compared earlier theoretical work. It is shown that pn-QRPA leads considerable improvement over gross theory calculations.
