A model for cold-fusion reactions related to the synthesis of super-heavy nuclei in collisions of heavy projectile-nuclei with a ²⁰⁸Pb target nucleus is discussed. In the framework of this model, the production of the compound nucleus by two paths, the di-nuclear system path and the fusion path, are taken into account simultaneously. The formation of the compound nucleus in the framework of the di-nuclear system is related to the transfer of nucleons from the light nucleus to the heavy one. The fusion path is linked to the sequential evolution of the nuclear shape from the system of contacting nuclei to the compound nucleus. It is shown that the compound nucleus is mainly formed by the fusion path in cold-fusion reactions. The landscape of the potential energy related to the fusion path is discussed in detail. This landscape for very heavy nucleus-nucleus systems has an intermediate state, which is linked to the formation of both the compound nucleus and the quasi-fission fragments. The decay of the intermediate state is taken into account in the calculation of the compound nucleus production cross sections and the quasi-fission cross sections. The values of the cold-fusion cross sections obtained in the model agree well with the experimental data.

^{与重弹丸-核与208}碰撞中超重核合成相关的冷聚变反应模型讨论了铅靶核。在该模型的框架内，同时考虑了双核系统路径和聚变路径两条路径产生复合核。双核体系框架内复合核的形成与核子从轻核向重核的转移有关。融合路径与从接触核系统到复合核的核形状的顺序演变有关。表明复合核主要由冷聚变反应中的聚变路径形成。详细讨论了与聚变路径相关的势能景观。这种非常重的核-核系统的景观有一个中间状态，这与复合核和准裂变碎片的形成有关。在计算复合核产生截面和准裂变截面时考虑了中间态的衰变。模型中得到的冷熔断面值与实验数据吻合较好。
