Abstract
High-Spin status of odd-odd Lu-166 were populated using the La-139(Si-30,3n gamma)Lu-166 at a beam energy of 120 MeV. Twelve new gamma-rays were place d on top of the previously known two rotational bands Guilt upon pi g(7/2) x vi(13/2) and pi h(11/2) x vi(13/2) Extending high-spin states up to 21(+) and 25(-) for each band, we have observed the onset of band crossing near h omega(c) approximate to 0.35 MeV. The band crossing frequency of the yras t pi h(11/2) x vi(13/2) band is consistent with the neutron BC band crossin g observed in lighter odd-odd Lu isotopes.
