The unit-helicity-flip and -nonflip amplitudes of gamma p yields p/ sup o/p and pi N yields pi N for I = 0 exchange are shown to be similar in magnitude when scaled by the vector-dominance-model constant. We separate the p/ sup o/ amplitudes for Pomeranchukon and f exchange using the dual absorption model. Possible sources of the helicity-flip term are discussed. (auth)
