Yrast states of /sup 160/Yb with spins up to 30h-bar were identified in the reaction /sup 148/Sm(/sup 16/O,4..pi gamma..). In addition to an initial backbend at I = 12h-bar, a second backbend occurs at I = 28h-bar. This result is discussed in terms of recently proposed explanations of the backbending effect.
