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.17enNuclear ReactionsSpectroscopy of <sup>166</sup>W and <sup>167</sup>W and alignment effects in very neutron-deficient tungsten nuclei198510.1016/0375-9474(85)90267-24243319151
