The 11B(α,γ0)15N reaction in the giant dipole resonance region
Keyword(s):
The 90° differential cross section of the 11B(α,γ0)15N reaction has been measured at α-particle energies from 5.74 to 17.80 MeV. The γ rays have been detected by a 23 cm long × 23 cm diameter NaI(Tl) crystal spectrometer enclosed in a plastic scintillator anticoincidence shield. The yield curve shows three well separated resonances at Eexc = 16.29 ± 0.15, 18.88 ± 0.20, and 21.26 ± 0.20 MeV.
