Abstract：
Within the O(6) limit of s-d IBM1, the effective three-body potential between the interactions of d-bosons is introduced with the consideration of octupole states, which are produced by a f-boson plus (N-1) s-d-bosons. Then the analytic expressions of positive and negative parity energy spectrum formula are obtained. Also the energy spectra of even-even nuclei ¹¹⁸Xe and ¹²⁰Xe are calculated. Good fits with the experimental data are obtained, and Staggering phenomena is quantitatively analyzed with Staggering index formula.
