Abstract：
High-spin level structure of ¹⁸⁸Au has been studied via the ¹⁷³Yb(¹⁹F, 4nγ) reaction using techniques of in-beam γ-ray spectroscopy. Based on the experimental results, the level scheme of ¹⁸⁸Au has been revised significantly. The previously reported positive parity levels have been modified and a new 20⁺ level was proposed to feed the 18⁺ states via two low-energy transitions. The existence of the 20⁺ and the level structures above it are similar to those in the neighboring odd-odd ^190,192Au,therefore, the π h_{11/2}^{-1}\otimes \upnu i_{13/2}^{-2} h_{9/2}^{-1} configuration was assigned to the 20⁺ state.
