Abstract
The elastic channel of the 8B + 58Ni system has been measured at energies around the Coulomb barrier. An optical potential fi to the experimental angular distributions is obtained. The total reaction cross section consistent with the obtained potential is reported and possible deviations from normal behaviour are discussed.
Keywords: Proton halo; elastic scattering.
