Measurements of the absolute cross section and angular distributions for theand the11B(α,α)11B reactions have been performed from 0.15 to 3.8 MeV for the11B(p,α) study and from 2 to 5.4 MeV for the11B(α,α) reaction. The absolute cross sections are presented in terms of the total number of α-particles detected in order to avoid uncertainties due to ambiguities in the number of alpha particles emitted in the reaction at a particular energy. The angular distributions of the11B(p,α)8Be(2+) reaction were fit to a Legendre polynomial expansion and the coefficients are presented. Finally, the11B(α,α)11B data were fit in terms of phase shifts (ignoring the spin of the target), providing a convenient representation of the elastic cross section data between 2 and 5.4 MeV.
