Abstract
High-spin states in the odd-odd 168Lu nucleus, populated in the
154Sm(19F,5n) reaction at a beam
energy of 96 MeV, were investigated using in-beam 
-ray
spectroscopy techniques. The BC neutron crossing in the yrast band, based on
![$\pi g_{7/2}[404]7/2^{+} ~{\bigotimes}~ \nu i_{13/2}[642]5/2^{+}$](/articles/epja/abs/1999/04/epja206/img2.gif){kind=small}
configuration, occurs at 
=0.31 MeV.
The two side bands, based on
![$\pi h_{11/2}[514]9/2^{-} {~\bigotimes ~} \nu i_{13/2}[642]5/2^{+}$](/articles/epja/abs/1999/04/epja206/img4.gif){kind=small}
and ![$\pi h_{9/2}[541]1/2^{-} {~\bigotimes ~} \nu i_{13/2}[642]5/2^{+}$](/articles/epja/abs/1999/04/epja206/img5.gif){kind=small}
configurations, show anomalous signature-splitting and
signature-inversion in the first one, to occur at =0.24 MeV.
A moderately delayed BC-crossing is anticipated
in the second one.
