Excitations in 94Ru were populated through the β+/ε decay of 94Rh following the fusion evaporation reaction 58Ni(40Ca,3pn)94Rh. Recoiling nuclei were implanted on the Yale moving tape collector at the Wright Nuclear Structure Laboratory, and delayed γ-rays were observed via an array of four Compton suppressed HPGe clover detectors. Nine new γ-transitions and five new levels were added to the level scheme of (π1g9/2)Jπ=6+4 level, in close agreement with prediction.
