The ${^3}He(e,e'd)p reaction in (q,omega)-constant kinematics

The cross section for the He-3(e, c' d)p reaction has been measured as a function of the missing momentum p(m) in (q, omega)-constant kinematics at beam energies of 370 and 576 MeV for values of the three-momentum transfer q of 412, 504 and 604 MeV/c. The L(+ TT), T and LT structure functions have been separated for q = 412 and 504 MeV/c. The data are compared to three-body Faddeev calculations, including meson-exchange currents (MEC), and to calculations based on a covariant diagrammatic expansion. The influence of final-state interactions and meson-exchange currents is discussed. The p(m)-dependence of the data is reasonably well described by all calculations. However, the most advanced Faddeev calculations, which employ the AV 18 nucleon-nucleon interaction and include MEC, overestimate the measured cross sections, especially the longitudinal part, and at the larger values of q. The diagrammatic approach gives a fair description of the cross section, but under(over)estimates the longitudinal (transverse) structure function. (C) 2002 Elsevier Science B.V. All rights reserved.
