[en] An experimental programme has been carried out at ELSA (ELectron Stretcher Accelerator) to investigate the four momentum transfer dependence of the N to Δ transition. In a series of electron scattering coincidence experiments on ¹H and ²D the -K²-range from 0.04 GeV²/c² to 0.8 GeV²/c² was sampled by measuring the υ_N^*, and φ_N^* angular distributions of the double differential pion production cross sections. The so determined ratio of the structure functions R_LT/R_TT at a-K² = 0.2 GeV²/c² is one of the first results obtained with the ELAN (Electron scattering collaboration at Bonn) time-of-flight spectrometer.

[en] The ratio of neutron and proton yields at quasifree kinematics was measured for the reactions ²H(e,e'n) and ²H(e,e'p) at momentum transfers Q²=0.125, 0.255, 0.417, and 0.605(GeV/c)², detecting the neutron and the proton simultaneously in the same scintillator array. The neutron detection efficiency was measured in situ with the ¹H(γ,π⁺)n reaction. From this the ratio R of ²H(e,e'n) and ²H(e,e'p) cross sections was determined and used to extract the neutron magnetic form factor Gⁿ_M in a model insensitive approach, resulting in an inaccuracy between 2.1% and 3.3% in Gⁿ_M
