Abstract

During the last decade we have carried out a systematic study of the β decay of neutron-deficient nuclei, providing rich spectroscopic information of importance for both nuclear structure and nuclear astrophysics. We present an overview of the most relevant achievements, including the discovery of a new exotic decay mode in the fp-shell, the β-delayed γ-proton decay in ⁵⁶Zn, the first observation of the 2⁺ isomer in ⁵²Co and the latest results on the heavier systems ⁶⁰Ge and ⁶²Ge. We also report on our deduced mass excesses in comparison with systematics and a recent measurement. Finally, we summarise our results on the half-lives of T_z = -1/2, -1 and -2 neutron-deficient nuclides, and analyse their trend.
