Abstract：
High-spin states in ⁸¹Rb were populated in the ⁵⁵Mn(³⁰Si, 2p2n) reaction at 130 MeV. Prompt γγγ-charged particle coincidences were observed using the GASP spectrometer in conjunction with the ΔE-E silicon ball (ISIS). A superdeformed band consisting of seven γ-ray transitions has been identified. The dynamic moment of inertia for the band is constant with a value of approximately 26.7 h²/MeV throughout the whole observed rotational frequency. This band is interpreted to have a π5¹v5² intrinsic intruder configuration with a quadruple deformation β₂ of 0.51.
