β Decay in the Region of Neutron-deficient 69,70,71Kr

Decay spectroscopy was performed for neutron-deficient nuclei ranging from zinc to krypton with isospin -3/2 <= T-z <= 0. Measurements of correlated beta-delayed protons allowed us to determine the isobaric analog states fed from the decay of Se-65 and Kr-69, constraining the spin of the Kr-69 ground state. Preliminary results regarding the half lives for the T-z = -1 systems, relevant to the rapid proton capture (rp) process, are discussed.
