High-spin states of odd-odd nuclei in the A∼170 mass region

Efforts have been made in our group to study the band structure of odd-odd nuclei in the A∼170 mass region. We aimed at providing new data of high-spin states and searching for the low-spin signature inversion in the 2-qp bands built on the πh9/2⊗νi13/2 and πi13/2⊗νi13/2 configurations. In this talk, main results of our work will be summarized, and some systematic features of signature inversion discussed. The spin and parity assignments for the πi13/2⊗νi13/2 band in 184Au could be regarded as firm providing a good example for systematic and theoretical investigations.
