Recent experimental results for the fusion of the weakly bound nucleus 9Be with spherical targets are analyzed by dynamical classical trajectories approach. In this approach, the Proximity model has been used to calculate the nuclear part of interaction potentials. Having determined the breakup functions and interaction potentials for 9Be + 124Sn, 89Y, 144Sm and 208Pb reactions, the complete and incomplete fusion (ICF) cross-sections are calculated by classical trajectories model and our results show a good description of the experimental data. We have stressed on the ICF probability (PICF) for chosen reactions. The obtained results show that the (PICF) based on our calculations are in a good agreement with both experimental data and empirical predictions [J. Hinde et al., Phys. Rev. Lett. 89, 272701 (2002)].
