The spectroscopy and structure of excited states of N ∼ Z nuclei in the mass 70–100 region has been investigated using two techniques. In the A ∼ 70–80 region fusion evaporation reactions coupled with the recoilβ-tagging method have been employed at Jyvaskyla to study low-lying states in odd–odd N = Z nuclei. Results from these and other data for known odd–odd nuclei above mass 60 will be discussed. In the heavier mass 90 region a fragmentation experiment has been performed using the RISING/FRS
setup at GSI. This experiment was primarily aimed at searching for spin gap isomers in nuclei around A ∼ 96. The objectives of the latter experiment will be discussed.
