Abstract
The harmonic-oscillator model for baryons is used to estimate the radiative widths of the observed resonances. In the "second resonance region" of pion photoproduction, both the and resonances [and possibly the , depending on what should be taken as its width] are expected to be important, while in the "third resonance region" , , and are expected to have comparable contributions. The mixing angle between the two resonances is determined to be about 35°. In inelastic electron scattering , the and resonances are expected to dominate over the . The neutral radiative width is found to be smaller than the charged width, in contrast to an assignment for this resonance.
