Cross sections were measured for the reaction 1H(e, e′π+) n at the energy W = 1.95 GeV and momentum transfer Q2 = 0.6 (GeV/c)2. At this W and Q2, the longitudinal cross section is dominated by t-channel production, giving a unique opportunity to examine the strong coupling form factor gπNN(t). The measured cross sections were separated using a method similar to a Rosenbluth separation. For the extraction of gπNN(t), the Actor and Körner model [42] and a parameterization of the MAID2000 …
