Abstract

We report on measurements on the reaction d(e, e'p)n in the invariant mass range of the final hadronic system 1.965 GeV ⩽ W ⩽ 2.335 GeV. At an average four-momentum transfer Q² = 0.23 (GeV/c)² the outgoing proton was detected at a c.m. angle θ_p = 80° in coincidence with the scattered electron. The measured differential cross sections are compared with theoretical calculations which include final state interactions, meson exchange currents and isobar contributions.

Electrodisintegration of the deuteron in the Δ-resonance region
1992, Nuclear Physics, Section A
A study of deuteron electrodisintegration has been performed as the first experiment at the new Bonn 3.5 GeV electron strecher and accelerator ELSA. This process was measured at an average four-momentum transfer Q² = 0.122 (GeV/c)² in the invariant hadron mass range of 2.02 – 2.30 GeV. The outgoing proton was detected in coincidence with the scattered electron at three different adjustments of the spectrometer (θ_p^lab = 44°, 56°, 68°). The measured differential cross sections show the influence of the excitation of the Δ(1232) resonance in the deuteron. The experimental results are compared to theoretical calculations which include meson exchange currents, final-state interactions and isobar currents.
