We have measured the cross sections and the analyzing powers for the ' C(p, y)"N reaction for proton energies from 4.0 to 16.2 MeV. The corresponding range in excitation energies, 13. 94 to 25.33 MeV, covers the region of the giant dipole resonance in '~N. The five-angle angular distributions measured with unpolarized and with polarized beams at eight energies over this region were analyzed to determine the magnitudes and relative phases of the transition matrix elements. The analysis included El, M1, and E2 transitions. The observed El strength exhausts only about 6% of the classical dipole sum rule. The dominant El strength is compared to a shell-model calculation which includes 3p-3h excitations. A fairly uniform distribution of E2 strength is observed which exhausts about 7% of the total energy-weighted sum rule. Although large uncertainties on this result could allow the existence of a giant E2 resonance, the most probable values indicate that no appreciable concentration of E2 strength is observed.
