Investigation of the 3He(e,e′pn)p reaction at MAMI — •P.J. Barneo — NIKHEF, Amsterdam, in collaboration with the Universities of Mainz, Tübingen and Glasgow.
The 3He(e,e′pn)p reaction has been studied in the spectrometer-hall of the A1-collaboration at MAMI (Mainz). Data were taken at an energy transfer of 220 MeV and three-momentum transfer of 375 MeV/c.
The reaction cross section is sensitive to nucleon-nucleon correlations in the three-nucleon system and the contributions of two-body mechanisms, i.e. intermediate Δ-excitation and meson-exchange currents.
The data analysis will be discussed and preliminary experimental results will be compared to existing data for the complementary reaction 3He(e,e′pp)n, measured at AmPS (Amsterdam), and to continuum Faddeev calculations of the Bochum group, performed with realistic NN interactions.
