Abstract：
Within the framework of the U _sdpf(16) interacting boson model, the effects of the octupole degree of freedom p- and f-bosons on the positive-parity states of even-even nuclei in rotational regions are discussed. It is shown that configurations of an even number of p-and f-bosons can not only be incorporated into the usual ground state band, β-, γ-vibrational bands, but also naturally form the K ^π=1 ⁺, 3 ⁺rotation bands, etc.. This result is similar to that of the U _sds(15)-IBM. The result is consistent with that of U _sd-IBM. E ₂transition probabilities are discussed briefly.
