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 recoil-β-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.
