| Abstract: | Proton inelastic excitation spectra of12C have been measured imposing a coincidence with alpha decay to8Beg.s. and8Be2.9MeV. In plane angular correlations have been obtained for the main structures observed in the spectra. Comparison with DWBA correlation functions permits a 2+ assignment for all the groups in the 20–30MeV excitation range. The percentage of theE2-EWSR exhausted in the same range is in agreement, within the uncertainties indicated, with that derived from the inelastic scattering of other particles. |
