Abstract：
Within the framework of the dinuclear system (DNS) model, the fusion reactions leading to the compound nuclei ²⁷⁴Hs^* and ²⁸⁶Cn^* are investigated. The fusion probability as a function of DNS excitation energy is studied. The calculated results are in good agreement with the available experimental data. The obtained results show that the fusion probabilities are obviously enhanced for the reactions located at high place in potential energy surface, although these reactions may have small values of mass asymmetry. It is found that the enhancement is due to the large potential energy of the initial DNS.
