  A selfconsistent approach based on a deformed HF+BCS+QRPA method with
density-dependent Skyrme forces is used to describe beta+ decay properties in
even-even deformed proton rich nuclei. Residual spin-isospin forces are
included in the particle-hole and particle-particle channels. The quasiparticle
basis contains neutron-neutron and proton-proton pairing correlations in the
BCS approach, while neutron-proton pairing interaction is treated as a residual
force in QRPA. We discuss the sensitivity of Gamow-Teller strength
distributions and beta+/EC half-lives to deformation, pairing and the strength
of the particle-particle interaction. The dependence on deformation is also
compared to that of spin M1 strength distributions.
