Experimental results of the elastic scattering of ${}^{6}$He on ${}^{208}$Pb at ${E}_{\mathrm{LAB}}=22$ MeV, measured at the CRC facility (Louvain-la-Neuve, Belgium), are presented, including results on the ${}^{4}$He 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 $\ensuremath{\alpha}$ particles indicates that such production is mostly generated by transfer to the continuum.
