摘要
The complete fusion channel of two approaching nuclei,including the interaction potential and fusion cross section,is systematically analyzed using the face-center-cubic(FCC)approach.For this purpose,we assume that the initial distribution of the nucleons in target and projectile nuclei is formed based on the FCC lattice model.Moreover,the density-dependent nucleon-nucleon interaction(CDM3Y6)is employed to parameterize the nuclear interactions between the participant nuclei.The obtained results for 45 fusion reactions reveal that the FCC+CDM3Y6 model is able to reproduce the corresponding experimental data of the barrier heights and positions within±10%,on average.The analytical calculations of the fusion cross section are performed by employing the coupled-channel approach which includes couplings to the low-lying2^(+) and 3^(-) states in target and projectile nuclei.It is shown that the theoretical values of the fusion excitation functions based on the selected microscopic framework are consistent with the experimental data.
