The elastic scattering and inclusive alpha-particle yield for the He-6 + Pb-206 system at an incident energy of 18 MeV, just below the nominal Coulomb barrier, have been measured. The alpha-particle yield at forward angles is also reported. The data are analyzed by means of continuum-discretized coupled-channels, distorted wave Born approximation, and coupled reaction channels calculations. Couplings to the one-neutron- and two-neutron-transfer reactions are found to be able to account for most of the absorption in the entrance channel.

Abstract
The elastic scattering and inclusive alpha-particle yield for the He-6 + Pb-206 system at an incident energy of 18 MeV, just below the nominal Coulomb barrier, have been measured. The alpha-particle yield at forward angles is also reported. The data are analyzed by means of continuum-discretized coupled-channels, distorted wave Born approximation, and coupled reaction channels calculations. Couplings to the one-neutron- and two-neutron-transfer reactions are found to be able to account for most of the absorption in the entrance channel.
