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.
Resumen
Se midió el canal elástico del sistema 8B + 58Ni a energías alrededor de la barrera Coulombiana. Se obtuvo un ajuste con potencial óptico a las distribuciones angulares experimentales. Se reporta la sección efica total de reacción consistente con el potencial obtenido y se discuten posibles desviaciones de comportamiento normal.
Descriptores: Halo protónico; dispersión elástica.
