Description
The reaction e + p → e' + n + π+ was studied detecting e' and π+ in coincidence at an invariant hadronic mass of 2.19 GeV. The measurements were performed at electron four-momentum transfers squared of Q2 = 0.06, 0.28, 0.70 and 1.35 GeV2. The differential cross section was found to be roughly independent of Q2 for Q2 > 0.7 GeV2 and abs. t abs. > 0.2 GeV2. (orig.)

Die Reaktion e + p → e' + n + π+ wurde durch Nachweis von e' und π+ in Koinzidenz bei einer invarianten Hadronenmasse von 2,19 GeV untersucht. Die Messungen wurden bei quadratischen Elektronen-Vierer-Impuls-Uebertraegen von 0,06, 0,28, 0,70 und 1,35 GeV2 durchgefuehrt. Der differentielle Wirkungsquerschnitt war fuer Q2 > 0,7 GeV2 und Betrag t Betrag > 0,2 GeV2 annaehernd unabhaengig von Q2. (orig.)
