Angular distributions and absolute cross sections have been measured for the N14(γ, p2) and N14(γ, p0) reactions, at giant resonance energies. The angular distributions are shown to be consistent with a model in which exclusively (p12)-1 (2s 1d) giant dipole states populate the C13 ground state by proton decay, and predominantly (p32)-1 (2s 1d) giant dipole states feed the 32- state of C13 at 3.68 MeV. Branching calculations based on established spectroscopic factors further support this model. It is inferred that the N14 dipole states of (p32)-1 (2s 1d) character, which carry ∼90% of the E 1 strength and which dominate the (γ, p2) process studied, do not contribute significantly to the (γ, p0) process which has often previously been treated as representative of E 1 absorption.
