Two-dimensional ..gamma..-ray energy correlations have been measured at high spins in /sup 146/Gd with the anti-Compton spectrometer array OSIRIS. Pronounced ridges have been found consisting of stretched E2 transitions. The separation of the ridges gives a dynamical moment of inertia 2theta/sup (2)//sub band/ = (150 +- 6)h-dash-bar/sup 2//MeV, suggesting a superdeformation with an axis ratio c/a = 1.7 (..beta../sub 2/approx. =0.6). The quadrupole moment of the superdeformed nucleus is Q/sub 0/ = 11/sub -4//sup +14/ exb. .AE
