Abstract
High-spin states in 166W and 167W were populated by the reactions 142Nd( 28Si,4n) 166W, 142Nd( 28Si,3n) 167W and 147Sm( 24Mg,4n) 167W. From the γ-decay the yrast band and a side band (with assumed negative parity) were identified to high spins. There is evidence for a second side band in 167W. The observed backbend of the yrast sequences and band-crossing anomalies in the side bands are discussed in conjunction with cranked-shell-model calculations. A systematic comparison is made between the yrast bands of 166,167,168W in order to understand the structure of the second backbend in 168W.
