The positive-parity doublet bands based on the {pi}h{sub 11/2}(multiply-in-circle sign){nu}h{sub 11/2} configuration in {sup 126}Cs were investigated in the two quasiparticles coupled with a triaxial rotor model. The energy spectra E(I), energy staggering parameter S(I)=[E(I)-E(I-1)]/2I,B(M1) and B(E2) values, intraband B(M1)/B(E2) ratios, B(M1){sub in}/B(M1){sub out} ratios, and orientation of the angular momentum for the rotor as well as the valence proton and neutron are calculated. After including the pairing correlation, good agreement has been obtained between the calculated results and the data available, which supports the interpretation of this positive-parity doublet bands as chiral bands.
