Abstract By the enlightment of the anharmonic vibrator description for the yrast bands of the even-even 38 ≤Z ≤82 nuclei with 2.05 ≤ R (= E_4⁺₁ / E_2⁺₁) ≤3.15, a similar regularity for the non-yrast bands is revealed. This systematics suggests that the excitations of the non-yrast bands may be regarded as the multi-phonon excitations above the corresponding bandhead, or the intrinsic states.
