Nb/sup 90/ produced by the (p,n) reaction on separated Zr/sup 90/ was studied by scintillation beta and gamma spectroscopic methods. The 14.56 plus or minus 0.05 hr activity emitted positions with an end point of 1.48 plus or minus 0.03 Mev and photons of 0.0176 plus or minus 2.330 plus or minus 0.010 Mev. Relative intensities of most of the transitions have been determined. The anisotropy of the 0.142 to 1.137 Mev cascade is -0.112 plus or minus 0.046. These measurements together with coincidence measurements have been used to assign the following levels (in Mev) and spins in the daughter nucleus Zr/sup 90/. 1.77 10+1, 2.20 12+1,
