  Beta-decay properties of neutron-rich Zr and Mo isotopes are investigated
within a microscopic theoretical approach based on the proton-neutron
quasiparticle random-phase approximation. The underlying mean field is
described self-consistently from deformed Skyrme Hartree-Fock calculations with
pairing correlations. Residual separable particle-hole and particle-particle
forces are also included in the formalism. The structural evolution in these
isotopic chains including both even and odd isotopes is analyzed in terms of
the equilibrium deformed shapes. Gamow-Teller strength distributions,
beta-decay half-lives, and beta-delayed neutron-emission probabilities are
studied, stressing their relevance to describe the path of the nucleosynthesis
rapid neutron capture process.
