论文摘要
本文总结了我们对导致冷和热融合反应中超重核形成反应机制的理解的最新进展。计算是在Jachimowicz等人的新核数据表中在逐散扩散（FBD）模型中完成的。 [在。数据nucl。数据表138，101393（2021）]。以标准方式将合成反应视为三步过程（即捕获，融合和生存）。分别分析每个反应步骤。将模型计算与所选的有关捕获，裂变样和融合横截面，融合概率以及蒸发残基激发功能的实验数据进行比较。详细讨论了角动量在融合步骤中的作用。为冷和热合成反应提供了一组具有相应融合概率的融合激发函数。
This article summarizes recent progress in our understanding of the reaction mechanisms leading to the formation of superheavy nuclei in cold and hot fusion reactions. Calculations are done within the Fusion-by-Diffusion (FBD) model using the new nuclear data tables by Jachimowicz et al. [At. Data Nucl. Data Tables 138, 101393 (2021)]. The synthesis reaction is treated in a standard way as a three-step process (i.e., capture, fusion, and survival). Each reaction step is analyzed separately. Model calculations are compared with selected experimental data on capture, fissionlike and fusion cross sections, fusion probabilities, and evaporation residue excitation functions. The role of the angular momentum in the fusion step is discussed in detail. A set of fusion excitation functions with corresponding fusion probabilities is provided for cold and hot synthesis reactions.
