Threshold electroproduction experiments and the axial vector form factor
Technical Report

OSTI ID:4938564
From international symposium on electron and photon interactions at high energies; Bonn, F. R. Germany (27 Aug 1973). Data from three coincidence experiments which measure the cross section for pi /sup +/ electroproduction around threshold are compared. Application of the PCAC motivated pseudovector Born approximation model yields corresponding values of the nucleon axial vector form factor for spacelike momentum transfer up to 0.6 GeV/sup 2/. Attention is paid to possible theoretical uncertainties and to the influence of the first pion- - nucleon resonance. (Recent single arm SLAC results are also included.) (auth)
