The scattering of 96-Mev protons from a carbon target has been investigated at laboratory angles between 3° and 90°. At the larger scattering angles, besides the elastic peak and inelastic continuum, inelastic peaks are found whose magnitude compares with the elastic peak. These inelastic proton peaks correspond to an excitation energy of the target nucleus of 4.4, 9.6, and 20.8 Mev. The angular distribution of elastically scattered protons shows slight diffraction minima at 40° and 64° (center-of-mass) after a careful separation of elastic from inelastic protons is made. The inelastic protons are peaked in the forward direction. Possible interaction models are discussed.
