A study of the reaction ¹⁰B(³He, d)¹¹C between 3.5 and 10 MeV

The ¹⁰B(³He, d)¹¹C reaction has been investigated over the energy range 3.5 to 10 MeV. Excitation functions for the ground state transitions were obtained at laboratory angles of 45°, 90°and 150°and detailed angular distributions were measured at bombarding energies of 3 7, 5 8, 7.5 and 9.8 MeV. The 150°excitation function shows a resonance at approximately 5 8 MeV, corresponding to an excitation of 26 MeV in the ¹³N system. This resonance, also observed in an earlier study of the ¹⁰B(³He, α)⁹B reaction, may be identified with giant resonance structure in ¹³N. A measurement of the total deuteron cross section by an activation method shows no evidence for the resonance. The (³He, d₀) angular distributions indicate the reaction to be predominantly a direct process and they have been fitted successfully using a distorted wave Born approximation analysis. Only a stripping mechanism is necessary to explain the forward and backward peaking.
