[en] Low-spin positive-parity yrare states of ₆₆¹⁵⁴Dy₈₈ were established using the ¹⁵⁵Gd(³He,4n) reaction at a beam energy of E_lab = 37.5 MeV. The AFRODITE spectrometer array at iThemba LABS was used to record γγ coincidences and measure DCO ratios and polarisation asymmetries. The K^π = 2⁺ γ band has been observed up to spin 13⁺ in the odd spins and to 12⁺ in the even spins. The staggering parameter S(I) of the γ band is compared to that found in other N = 88 isotones. Different behaviour of S(I) with increasing spin is observed for each of the isotones. We conjecture that the variation in S(I) is mainly due to mixing of the even-spin states with the same spin and parity states in neighbouring rotational bands. A second K^π = 2⁺ band has been established up to a spin of 12⁺ in the even spins. We suggest that this is a γ band based on the J^π = 0⁺ state at E_x = 660.6 keV. (orig.)
