The angular distributions of protons scattered elasti- cally and inelastically by N, Ne, Mg, Si, S, and Ar nuclei were studied at several values of proton energy from 7.6 to 14.2 Mev. The distribution shapes for elastic scattering show general diffraction patterns at E/sub p/ > 10 Mev. While the yields of inelastic scattering corresponding to the second excited state of N/sup 14/ are appreciable at higher energies, the yields for the first excited state with T = 1 are markedly low. The inelastic scatterings for the first excited states of Ne/sup 20/, Mg/sup 24/, and Si/sup 28/ are found to change their distribution shapes appreciably with proton energy. The excitation functions of the reaction for Si/sup 28/ were also studied. The results show prominent resonance features. These results seem to support the proposition that the formation of a compound nucleus plays an appreciable role in the inelastic scattering from these light nuclei, especially at the lower energy. The distribution shapes of the inelastic scattering from S/sup 32/ are fairly insensitive to energy change. Further, the inelastic scattering of protons from Ar/sup 40/ shows quite a different feature from those mentioned above. The angular distribution shapes and their energy dependences resemble much those obtained for medium weight eveneven nuclei. (auth)
