We have identified yrast states of /sup 152/Dy to spin approx.37, with unusually strong population of high-spin states in the (/sup 32/S, 4n..gamma..) reaction. Yrast isomers with spins approx.17, 21, 27, and 31 were detected. For I > or = 14 the yrast states scatter about a straight line on an E vs I (I + 1) plot, consistent with predictions for aligned-particle configurations. The slope of the line yields an effective moment of inertia 18% larger than the rigid-sphere value. This and other arguments suggest possible oblate deformation at high spin.
