Abstract: Five rotational bands with configurations {π7/2+[404] ⊗ν5/2+[642]} K = 6, {π9/2-[514] ⊗ν5/2+[642]} K = 7, {π1/2+[411] ⊗ν5/2+[642]} K = 2, {π1/2-[541] ⊗ν5/2+[642]} K = 2 and {π5/2+[402] ⊗ν5/2+[642]} K = 5 were populated through the 152Sm ( 19F, 5n) 166Lu reaction at a beam energy of 97MeV. The last three bands are identified in the present study. A phase change of level staggering is observed and low-spin signature inversion is suggested in the band {π1/2-[541] ⊗ν5/2+[642]} K=2. The inversion spin 17.5? (spin at inversion point) of this band fits well to the systematic variation trend of inversion spin, increasing with N and decreasing with Z, for the known π1/2-[541] ⊗νi 13/2 bands observed in odd-odd deformed nuclei around A = 170.
