摘要
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.
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.
