The projectile-target system [sup 40]Ca+[sup 58]Ni has been used to produce the neutron deficient [ital N]=50 isotones [sup 93]Tc, [sup 94]Ru, and [sup 95]Rh at high angular momentum. The multidetector array NORDBALL including particle selection was used. A large number of new levels were found in all three nuclei. Most of them can be interpreted as states with a neutron particle-hole excitation across the [ital N]=50 shell gap, coupled to lower valence-proton configurations. Some of the observed levels above 11 MeV probably correspond to states with two neutrons excited across the shell gap.
