Abstract By comparing quadrupole moments between the interacting boson model (IBM) and the collective model, a simple calculation for the triaxial deformation parameters β and γ in the O(6)-like nuclei is presented, based on the intrinsic frame in the IBM. The systematics of the β and γ are studied. The realistic cases are calculated for the even-even Xe, Ba, and Ce isotopes, and the smooth dependences of the strength ratios θ₃/ and the effective charges e₂ on the proton and neutron boson numbers N_π and N_v are discovered.
