Charge-exchange reaction induced by 6He and nuclear densities

The charge-exchange reaction p(6He,6Li)n is studied in reverse kinematics with a secondary 6He beam at 41.6 MeV/nucleon. The transition connecting the ground state of 6He to its isobaric analog state in 6Li has been measured and analyzed in the context of a microscopic calculation. The angular distribution is shown to be sensitive to the nuclear interaction potential and to the radii of the density distribution of 6He. It is shown that only a coherent microscopic analysis may disentangle the different contributions. (orig.)
