Search for the chiral Band in the N=71 Odd—odd Nucleus ^126Cs

High-spin states in ^126Cs are studied via the ^116Cd(^14N,4n) reaction at a beam energy of 65MeV.The sideband of the πvh11/2 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 πh11/2 vh11/2 bands are proposed to be candidates for chiral doublet bands in ^126Cs.
