Search for the Halo Effect in the ¹H(⁶He, ⁶Li)n Reaction

The angular distributions of the charge exchange reaction ¹H(⁶He, ⁶Li)n were measured in reverse kinematics with a secondary ⁶He beam at the energy of 4.17 A MeV. The data were analysed in the context of a microscopic calculation. It is shown that both the ground state of ⁶He and the second excited state of ⁶Li (3.563MeV, 0⁺) have a halo structure.
