Abstract

The reaction e^-+p→e^-+p+π^o has been studied in the region of the first pion nucleon resonance. Four sets of data have been analysed at nominal values of the squared four-momentum transfer to the pion nucleon system, k², of 0.3, 0.45, 0.6 and 0.76 (GeV/c)². We present results on the variation with k² of the multipole amplitudes M₁₊, E₁₊, S₁₊ which contribute to the resonant partial wave and we also discuss the behaviour of E_o+, S_o+ and M_1- contributing to the S and P-wave backgrounds.
