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 configuration, occurs at =0.31 MeV. The two side bands, based on and 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.
