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 $\gamma$ -ray spectroscopy techniques. The BC neutron crossing in the yrast band, based on $\pi g_{7/2}[404]7/2^{+} ~{\bigotimes}~ \nu i_{13/2}[642]5/2^{+}$ configuration, occurs at ${\hbar}{\omega}$ =0.31 MeV. The two side bands, based on $\pi h_{11/2}[514]9/2^{-} {~\bigotimes ~} \nu i_{13/2}[642]5/2^{+}$ and $\pi h_{9/2}[541]1/2^{-} {~\bigotimes ~} \nu i_{13/2}[642]5/2^{+}$ configurations, show anomalous signature-splitting and signature-inversion in the first one, to occur at ${\hbar}{\omega}$ =0.24 MeV. A moderately delayed BC-crossing is anticipated in the second one.
