摘要：

Predictions axe made for the photoproduction amplitudes of low-lying N1/2+ (P11) and DELTA-3/2+ (P-33) resonances, using a quark model with relativistic corrections to the transition operator, and mixed nonrelativistic wave functions which axe correctly orthogonal to the ground states. These amplitudes are also calculated using relativized model wave functions. The results for the Roper resonance N(1440) are in marked disagreement with the data.
