Abstract

The 3He+3He differential scattering and reaction cross-section data in the energy range of 1.5 to 15 MeV (c.m.) is analyzed with a one-channel resonating-group method to which is added a phenomenological imaginary potential in order to approximately account for open reaction channels. With a nucleon-nucleon potential of near-Serber exchange mixture it is found that satisfactory results can be obtained with such a formalism. The presence of the imaginary potential is shown to be important, especially at higher energies; it affects the magnitude of the differential cross section mainly, but can also accentuate the diffraction features at certain energies.
