The angular distributions have been obtained for alpba-particles from the reactions Be^9 (ρ,α) Li^6 (ground state), Be^9 (d,α) Li^7 (ground, first and second excited states), B^<10>(ρ,α) Be^7 (ground state), B^<10> (d,α) Be^8 (ground state), B^<11> (ρ,α) Be^8 (ground state) and B^<11> (d,α) Be^9 (ground and second excited states), and from the elastic and inelastic (second excited state) scatterings of alpha-particles by Be^9. Besides, the angular distribution of deuterons from the reaction Be^9 (ρ,d) Be^8 (ground state) was measured. The energies of incident beams were nearly 7 MeV for protons, 14 MeV for deuterons and 28 MeV for alpha-particles. The results, except for B^<1> (ρ,α) Be^7 and B^<11> (ρ,α) Be^8, show forward and/or backward rises and may be interpreted by direct interactions. The integrated cross sections of the reactions (ρ,α) and (d,ぴ) on Be^9 are larger than those on B^<10> and B^<11>.
