Abstract

The high-spin states of ¹⁵⁷Yb have been studied via the reaction of ¹⁴⁴Sm(¹⁶O, 3n) at ¹⁶O energy of 90 MeV using techniques of in-beam γ-ray spectroscopy. Measurement of γ- γ-t coincidences was performed with 11 BGO(AC)HPGe detectors. Based on the γ-γ coincidence relationships and the measured results of γ-ray anisotropies and DCO ratios, the level scheme for ¹⁵⁷Yb was established. The shape co-existence and structural evolution of the vi _13/2 band with increasing angular momentum in ¹⁵⁷Yb have been discussed. The systematics of the vi_13/2 bands in the N= 87 odd-A isotones have been compared.
