The angular distributions of the 11B(α,γ0)15N and 12C(3He, γ0)15O reactions have been measured at several energies over the giant dipole resonance (GDR) of the two residual nuclei. The 90° yield curve of the 11B(α,γ0)15N reaction has been remeasured with improved energy resolution over the energy ranges Eα = 6.89 – 8.0 and 12.8 – 15 MeV. The γ-rays were detected by a 23-cm long × 23-cm diameter NaI(Tl) crystal spectrometer enclosed in a plastic scintillator anticoincidence shield. Spins and parities of the resonances observed in the yield curves were obtained; the structure previously observed in the yield curve of the 11B(α, γ0)15N reaction between Eα = 7 and 8 MeV has been resolved into two peaks.
