Abstract

The yrast sequence in ${}^{168}{Hf}$ has been extended to $I^{π} = 34^{+}$ and two negative-parity side-bands have been observed to $I^{π} = 33^{-} and 30^{-}$ . At high rotational frequencies all three bands have little spin alignment and have moments of inertia which remain constant as a function of frequency. Possible evidence for the vanishing of pairing correlations is discussed.
