摘要

The high-spin states of~(157)Yb have been studied via the~(144)Sm(~(16)O,3n)~(157)Yb reaction at~(16)O energy of 90 MeV by using techniques of in-beam γ-ray spectroscopy.Measurement of γ-γ-t coincidences was performed with 11 BGO(AC)HPGe derectors.Based on the measured resuIts of γ-γ coincidences,γ-ray anisotropies and
