Abstract

The ep -> e(')pi(+)n reaction was studied in the first and second nucleon resonance regions in the 0.25 GeV2< Q(2)< 0.65 GeV2 range by use of the CLAS detector at Thomas Jefferson National Accelerator Facility. For the first time, to our knowledge, the absolute cross sections were measured, covering nearly the full angular range in the hadronic center-of-mass frame. We extracted the structure functions sigma(TL),sigma(TT), and the linear combination sigma(T)+epsilon sigma(L) by fitting the phi dependence of the measured cross sections and compared them with the MAID and Sato-Lee models.
