✦ Synopsis

We analyze fusion cross sections induced by the 6 He halo projectile in the framework of the double folding SΓ£o Paulo potential, which has been shown to be a reliable potential for the analysis of fusion cross sections induced by stable weakly bound nuclei. The results show that the fusion cross sections of 6 He + 209 Bi, 238 U are suppressed at energies above the barrier, when compared with coupled channel calculations that do not take into account the projectile breakup, whereas they are in agreement with the calculations at sub-barrier energies.

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 dist
