摘要
The interaction of He-6 with Bi-209 has been studied over a range of energies well below the nominal Coulomb barrier. A He-4 group of remarkable intensity, first observed in a previous experiment at near-barrier energies, continues to dominate the reaction in the sub-barrier regime. A total cross section of nearly 200 mb was measured for this group at 6 MeV below the barrier. This very large value is shown to be consistent with the total reaction cross section deduced from a simultaneously-measured elastic scattering angular distribution.
