Elastic scattering and direct reactions of the 1n halo super(11)Be nucleus on super(64)Zn near the barrier

Elastic scattering and direct reactions have been studied for the collisions induced by the three Beryllium isotopes super(9,10,11)Be, on a medium mass super(64)Zn target at energies near the Coulomb barrier. The elastic-scattering angular distribution of the 11Be halo nucleus shows a deviation from...

Summary:Elastic scattering and direct reactions have been studied for the collisions induced by the three Beryllium isotopes super(9,10,11)Be, on a medium mass super(64)Zn target at energies near the Coulomb barrier. The elastic-scattering angular distribution of the 11Be halo nucleus shows a deviation from the classical Fresnel type diffraction behavior in the Coulomb-nuclear interference peak angular region. The deduced total reaction cross-sections for the super(11)Be collision is more than a factor of two than the ones measured in the collisions induced by super(9; 10)Be. Moreover, for super(11)Be a large contribution to the total reaction cross-section due to transfer and break-up processes has been observed.
