Abstract：
Within the framework of the Usdpf (16) interacting boson model, effects of theoctupole degree of freedom p-and f-bosons on the positive-parity states of even-evennuclei in rotational regions are discussed. It is shown that configurations of an evennumber of p-and f-bosons not only can be incorporated into the usual ground stateband, β- ．γ-vibrational bands, but also naturally form the Kπ=1+.3+ rotational bandsetc. This result is similar to that of the Usdg (15)-IBM. Besides, E2 transition probabilities are discussed briefly.
