2025-11-25 Research Progress in Nuclear Fusion Reactions doi:10.57760/sciencedb.j00213.00238 en The high-precision calculation of heavy ion capture cross section is one of the key factors determining the final fusion reaction evaporation residual cross section, which is extremely important for studying atomic nucleus structure, exploring fusion mechanism, and screening the optimal incident energy for superheavy nucleus synthesis. Table 1 summarizes the comparison results between experimentally observed fusion cross-sections and theoretical models (empirical coupled-channel model, empirical barrier distribution method, CCFULL model, the universal Wong formula, improved quantum molecular dynamics model) at corresponding incident energies in four fusion reaction systems of light nuclei and light nuclei; Table 2 lists 11 light to medium heavy nuclear reaction systems, and compares the experimentally observed fusion cross-sections with the theoretical model at the incident energy; Table 3 selects 8 heavy nuclei-heavy nuclei reaction systems and compares the experimentally observed capture cross sections with the theoretical model calculation results at the incident energy. To evaluate the descriptive effect of the different models on the capture cross section experimental data mentioned above, Figure 3 takes the 16O+144Sm reaction system as an example to show the relationship between the theoretical calculation and experimental observation of the capture cross-section with the change of incident energy. fusion reaction; nuclear reaction model; capture cross section; evaporation residue section Zhang Yuhai Dong Yifei Zhong Jiayong Zhang Fengshou PUBLIC https://creativecommons.org/licenses/by-nc-nd/4.0/ dataset http://www.doi.org/10.7498/aps.75.20251346 Science Data Bank
