The fusion of $\chem{^{6}He}$ with a $\chem{^{209}Bi}$ target displays a large enhancement at energies near to and below the Coulomb barrier. Recently, a $\chem{^{4}He}$ group of remarkable intensity, which dominates the total reaction cross-section, has also been observed in the near-barrier interaction of the same system. It is argued that this transfer/breakup channel acts as a doorway state to fusion.
