Abstract： High spin states of 94Nb have been studied with the 82Se(18O, p5n)94Nb fusion evaporation reaction at anincident beam energy of 82and 88 MeV. The level scheme of 94Nbhas been modified and extended with 15 newγrays. Based on γ-γcoincidence relationships，DCO ratios and linear polarization measurements, the new level structures in 94Nb have been interpreted in terms of the shell model calculations performed in the configuration space π(1f5/2, 2p3/2, 2p1/2, 1g9/2 ) for the protons and ν(2p1/2, 1g9/2, 1g7/2, 2d5/2 ) for the neutrons.
