A search for the lowest 2/sup +/ state in /sup 146/Gd using (..cap alpha.., 2n..gamma..) excitation function measurements near threshold has located that state at 1971 keV. Its energy, more that 300 keV higher than in any other n = 82 nucleus, provides clear spectroscopic evidence for a large gap in the single-particle spectrum at Z = 64.
