The level scheme of /sup 86/Zr was studied by in-beam measurements on ..gamma.. transitions in the /sup 60/Ni(/sup 29/Si,2pn..gamma..)/sup 86/Zr reaction and by helium-jet studies of delayed ..gamma..-ray activity from the /sup 58/Ni(/sup 32/S,3pn)/sup 86/Nb(..beta.. +/EC)/sup 86/Zr reaction. In the latter study, measurements consisted of ..gamma..-..gamma.. and ..beta..-..gamma.. coincidences, excitation functions, and a lifetime determination. An /sup 86/Nb decay scheme was obtained which suggests J/sup ..pi../ = 5/sup +/ for the /sup 86/Nb ground state. The in-beam study consisted of ..gamma..-..gamma.. coincidences, excitation functions, angular distributions, and lifetime measurements via both Doppler shift attenuation and recoil distance methods. The high-spin decay scheme and level lifetimes obtained from the in-beam studies suggest intrinsic modes of excitation rather than the collective behavior seen in /sup 84/Zr.
