The optical potential of 6He in the eikonal approximation Original Research Article

The new data of the elastic scattering of 6He+12C at about 40 MeV/nucleon are analyzed in the eikonal approximation. The 6He+12C phase-shift function is evaluated completely without any ad hoc assumption by a Monte Carlo integration, which makes it possible to use a realistic 6-nucleon wave function for a halo nucleus 6He. The effect of the breakup of 6He on the elastic differential cross sections as well as the optical potential is studied at different energies from 40 to 800 MeV/nucleon.
