Backward electroproduction of π+ mesons in the second and third nucleon resonance region

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

The reactionep→enπ + has been studied in the invariant mass range of 1.44≦W≦1.83 GeV. The outgoing pion was detected in the backward direction (cosλ * π ≦-0.94) with respect to the virtual photon at four-momentum transfers of 0.4≦q 2≦0.7 (GeV/c)2. The values of the helicity-1/2-partial wave amplitudesA 2−(D 13(1520)) andA 3−(F 15(1688)) were determined by a phenomenological analysis and compared with single quark transition models (S.Q.T.M.).
