Abstract

The reactions (α, 3nγ) and (α, α′nγ) on 88Sr, 90Zr and 92Mo were used to populate excited states in 89Zr, 91Mo and 93Ru. The de-excitation of these states was studied by in-beam γ-ray spectroscopy. The short-lived radioactivity of the 92Mo target was measured in order to study the decay of 93Ru. Many new levels were observed, particularly in 91Mo. They are interpreted as due to the coupling of a g92 neutron hole with known excited states in 90Zr, 92Mo and 94Ru.
