Abstract

We report on measurements of the reactionep→enπ+ in the region of theD 13(1520) andF 15(1688) resonances. At an invariant four-momentum transferq 2=0.3 (GeV/c)2 the outgoing pion was detected in the forward and backward directions. The values of the helicity-1/2-partial wave amplitudesA 2−(D 13(1520)) andA 3−(F 15(1688)) are determined from these measurements. A comparison of the results with single quark transition models is made.
