Experimental results of the elastic scattering of He-6 on Pb-208 at E-LAB = 22 MeV, measured at the CRC facility (Louvain-la-Neuve, Belgium), are presented, including results on the He-4 production channel. These data were taken with full angular coverage and high angular resolution. Both experimental cross sections are compared with continuum discretized coupled channels and distorted-wave Born approximation calculations, where direct breakup and transfer to the continuum processes are considered. The elastic data confirm the absence of the Coulomb rainbow, while the distribution of alpha particles indicates that such production is mostly generated by transfer to the continuum.
