在双核系统模型中，研究了相互作用变形核的相对取向对产生超重元素的冷聚变反应的相互作用势能面和蒸发残余截面的影响。研究了聚变和准裂变之间的竞争，以说明取向的影响。事实证明，腹腹取向有利于超重核的产生，因为在这种情况下，屏障抑制了准裂变，从而有助于聚变。
Within the dinuclear system model, the effects of the relative orientations of interacting deformed nuclei on the interaction potential energy surfaces, the evaporation residue cross sections of some cold fusion reactions leading to superheavy elements are investigated. The competition between fusion and quasifission is studied to show the effect of the orientation. It turns out that the belly-belly orientation is in favor of the production of superheavy nuclei, because in the case a barrier has suppressed the quasifission and thus helped fusion.
