• Using 〜22-MeV alpha particles the angular distributions of protons from (α, p) reactions on B^<10>, C^<12>, N^<14>, Na^<23>, Mg^<24>, P^<31>, S^<32>, Ca^<40>, Sc^<45>, Mn^<55>, Fe^<54>, Fe^<56> and Co^<59> were measured. The angular distributions on the light nuclei show diffraction-like patterns, but those on the mediumweight nuclei are peaked at forward angle and decrease monotonically with angle. These angular distributions are fitted with theories of a stripping reaction. At first they are compared with a theory obtained by using plane-wave approximation for wave functions of incoming alpha particles and outgoing protons. They are also compared with a theory using a simple distorted-wave approximation which fits better with the experimental results. The values of parameters in the theoretical formula show systematic differences in cases that tritons are captured by target nuclei with angular momenta 0 and 2. Some results on spectroscopic investigations of the target or residual nuclei are also discussed. The (α, p), (α, n) and (p, α) reactions have a strong energy dependence near 20-MeV excitations (the giant resonance region), and above this region their energy dependences become smaller.
