Protons acceleratcd the 105 cm cyclotron of Kyoto University were used to investigate the energy dependence of the angular distributions and the reaction mechanism of the inelastically scattered protons from the odd-even nuclei, B^<11>, F^<19>, Al^<27> and P^<31> at 6.0 〜 7.5 MeV using conventional electronic techniques. It was found that (a) the energy dependence of the angular distribution has close relation to the excitation energy of the compound system, namely above the excitation energy of about 13 MeV in the compound system, many patterns of the angular distributions including that of the light even-even nuclei were relatively energy-independent: (b) Total cross sections were considerably smaller than that of the neighbouring even-even nuclei and less energy-dependent: (c) In the case of F<19> the shapes of the angular distributions suggested the existence of a direct interaction: (d) The relative yields from the various levels of Al^<27> might have some relation to its nuclear structure in the Nilsson model.
