Findings

Calculated beta-decay half-lives agree with experimental data.

Neutron-emission probabilities are estimated for the isotopes.

Method highlights advantages and limitations compared to previous models.

Abstract

In this work we studied $\beta$-decay properties for deformed neutron-rich nuclei in the region Z=36-43. We use the deformed pn-QRPA methods with the realistic CD-Bonn forces, and include both the Gamow-Teller and first-forbidden types of decays in the calculation. The obtained $\beta$-decay half-lives and neutron-emission probabilities of deformed isotopes are compared with experiment as well as with previous calculations. The advantages and disadvantages of the method are discussed.
