运用了Ｕｓｄｐｆ（１６）相互作用玻色子模型讨论了八极自由度Ｐ和ｆ玻色子对转动区偶偶核正宇称态的效应．结果表明，偶数个Ｐ和ｆ玻色子的组态能够混入到通常的基态带，β和γ振动带，并且自然地形成Ｋπ＝１＋、３＋等转动带．这一结果与Ｕｓｄｇ（１５）－ＩＢＭ相类似．本文还简要地给出了基态带间的Ｅ２约化跃迁几率，其结果与Ｕｓｄ（６）－ＩＢＭ相一致． The Usdpf (16) interacting boson model is used to discuss the effect of octuple degrees of freedom P and f bosons on the positive parity of even-even kernels in a rotating region. The results show that the configuration of even-numbered P and B bosons can be mixed into the usual ground-state bands, β and γ vibration bands, and naturally form rotation bands such as Kπ = 1 +, 3 +. This result is similar to Usdg (15) -IBM. This article also gives a brief summary of the transition probability of the reduction of E2 between ground-state bands. The result is consistent with that of Usd (6) -IBM.
