摘要：

The peculiar structure of the halo nuclei is expected to strongly influence the reaction dynamics at energies around the Coulomb barrier. In this paper we will summarize the main experimental results obtained by different authors on the above topic. Our recent results concerning the study of the collisions (9,10,11)Be+(64)Zn and (4,6)He+(64)Zn will be discussed more in detail. It is observed that the total reaction cross section with halo nuclei is dominated by direct reactions. A complete agreement on the effects of the halo structure on the fusion cross section is not yet reached by different authors.
