摘要: High-spin states in the odd-odd 168Lu nucleus, populated 154Sm(19F,5n) reaction at a beam energy of 96 MeV, were investigated using in-beam γ-ray spectroscopy techniques. The BC neutron crossing yrast band, based on πg7/2[404]7/2+⊗νi13/2[642]5/2+ configuration, occurs ħω= 0.31 MeV. two side bands, πh11/2[514]9/2−⊗νi13/2[642]5/2+ and πh9/2[541]1/2−⊗νi13/2[642]5/2+ configurations, show anomalous signature-splitting signature-inversion first one, to occur 0.24 A moderately delayed BC-crossing is anticipated second one.
