Abstract High-spin states in ¹²⁶Cs are studied via the ¹¹⁶Cd(¹⁴N, 4n) reaction at a beam energy of 65 MeV. The sideband of the πh_11/2 vh_11/2 yrast band, a ΔI = 2 band known from previous study, is developed into a ΔI = 1 coupled structure at low spins. This sideband is assigned to be built on the same configuration as the yrast band according to the measured ratios of directional correlation of orientation and observed alignment properties. On the basis of comparisons with the previously proposed chiral doublet bands for ^128,130Cs, the observed two πh_11/2 vh_11/2 bands are proposed to be candidates for chiral doublet bands in ¹²⁶Cs.
