Absolute differential cross sections are given for the elastic scattering by silicon of 9.45 MeV, 9.28 MeV, 8.96 MeV, 8.55 MeV and 7.97 MeV protons for an angular range of 15°-156° (centre-of-mass coordinates). The angular distributions show characteristic maxima and minima, the patterns varying slowly with energy as might be expected for scattering by a complex potential. Absolute differential cross sections for the inelastic scattering of protons at these five energies from the 1.78 MeV level of 28 Si are also given. All the inelastic angular distributions are asymmetric about 90° with a forward peaking. The magnitude of the asymmetry varies with energy and is greatest at 8.96 MeV.
