The Analytical Parametrization of Fusion Barrier by Using the Skyrme Energy-Density Function Model

Communications in Theoretical Physics 2015年第8期64卷 177-184页

Using the skyrme energy density formalism, a pocket formula is introduced for barrier heights and positions of 95 fusion reactions(48≤ZPZT≤1520) with respect to the charge and mass numbers of the interacting nuclei. It is shown that the parameterized values of RBand vBare able to reproduce the corresponding experimental data with good accuracy. Moreover, the absolute errors of our formulas are less than those obtained using the analytical parametrization forms of the fusion barrier based on the proximity versions. The ability of the parameterized forms of the barrier heights and its positions to reproduce the experimental data of the fusion cross section have been analyzed using the Wong model.

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)*** this purpose,we assume that the initial distribution of the nucleons in target and projectile nuclei is formed based on the FCC lattice ***,the density-dependent nucleon-nucleon interaction(CDM3Y6)is employed to parameterize the nuclear interactions between the participant *** 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 *** 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 *** is shown that the theoretical values of the fusion excitation functions based on the selected microscopic framework are consistent with the experimental data.
