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 Tz
-1/2, -1 and -2 neutron-deficient nuclides, and analyse their trend.
