【 摘 要 】

In this paper an overview of different results concerning elastic scattering in collisions induced by halo nuclei will be given. Due to the very low binding energy of such nuclei, coupling effects with the break-up channel have been found to be very important. Moreover, due to the long tail of the density distribution of halo nuclei and the presence of a large low-lying dipole strength distribution, long range absorption affects the elastic scattering angular distribution. In the paper the main effects responsible for the observed features in the scattering cross-section will be discussed.
