Abstract
The high-spin states of157Yb have been studied via the reaction of144Sm(16O, 3n) at16O 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 for157Yb was established. The shape co-existence and structural evolution of thevi13/2 band with increasing angular momentum in157Yb have been discussed. The systematics of thevi13/2 bands in theN=87 odd-A isotones have been compared.
