Abstract

The absolute cross section and angular distribution for the N14(γ,p0) process have been measured, in the giant-resonance energy range from 17 to 25 MeV. Between 17 and 21 MeV, the large angular anisotropy requires mixing of at least two dominant E1 reaction channels. Above 22 MeV, d-wave emission from 2 states appears to dominate. Admixture of about 5-10% of E2 and/or M1 strength is observed at all energies. The observations are qualitatively consistent with the shell-model predictions of Cooper and Eisenberg.
