High-spin structure in odd-odd ¹⁶⁰Lu nucleus

The high-spin states of ¹⁶⁰Lu are populated by the fusion-evaporation reaction ¹⁴⁴Sm(¹⁹F, 3n)¹⁶⁰Lu at beam energies of 90 and 106 MeV. A new level scheme of ¹⁶⁰Lu is established. A possible isomeric state based on the πh_11/2⊗νh_9/2 configuration is observed. The new decoupled band with the configuration of πd_3/2[411]1/2⁺⊗νi_13/2[660]1/2⁺ is established, and the configurations of these similar decoupled bands in the neighboring odd-odd ^162-166Lu nuclei are suggested. A positive parity coupled band is assigned as the πd_5/2 [402]5/2⁺⊗νi_13/2[660]1/2⁺ configuration. (authors)
