Quasielastic scattering of 8B and 7Be on 12C at 40 MeV/nucleon
Abstract
The quasielastic scattering of the exotic nucleus 8B on a 12C target has been studied at an energy of 320 MeV and compared with that of 7Be at the same velocity. The quasielastic scattering of 12C + 12C at 20 MeV/nucleon, also performed as a secondary beam experiment, was used to check the data reduction method. The results are interpreted in terms of a semimicroscopic double folding model and coupled-channels calculation. The difference in the total reaction cross section (8%) between 8B and 7Be is consistent with the measured one proton removal cross section and corresponds to an increase in the interaction radius of 4%. The existence of a substantial proton halo in 8B is not supported by the present data.
