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 γ-ray spectroscopy techniques. The BC neutron crossing in the yrast band, based on πg 7/2[404]7/2+⊗νi 13/2[642]5/2+ configuration, occurs at ħω= 0.31 MeV. The two side bands, based on πh 11/2[514]9/2−⊗νi 13/2[642]5/2+ and πh 9/2[541]1/2−⊗νi 13/2[642]5/2+ configurations, show anomalous signature-splitting and signature-inversion in the first one, to occur at ħω= 0.24 MeV. A moderately delayed BC-crossing is anticipated in the second one.
