Abstract

High-precision ¹H(e, e^lp)φ⁰ measurements at Q² = 0.126 (GeV/c)² are presented. It allows the determination of quadrupole amplitudes in the γ^*N → △ transition, in which the reliability of electroproduction models was simultaneously tested. The derived quadrupole-to-dipole (I = 3/2) amplitude ratios, R_SM = (-6.5 ± 0.2_stat+sys ± 2.5_mod)% and R_EM = (-2.1 ± 0.2_stat+sys ± 2.0_mod)%, are dominated by model error.
