Phys. Rev. Lett. 87, 172301 (2001) [4 pages]Relativistic Effects and Two-Body Currents in 2H(e→,e′p)n Using Out-of-Plane Detection |
Received 14 May 2001; published 3 October 2001
Measurements of the 2H(e→,e′p)n reaction were performed with the out-of-plane magnetic spectrometers (OOPS) at the MIT-Bates Linear Accelerator. The longitudinal-transverse, fLT and fLT′, and the transverse-transverse, fTT, interference responses at a missing momentum of 210 MeV/c were simultaneously extracted in the dip region at Q2 = 0.15 (GeV/c)2. In comparison to models of deuteron electrodisintegration, the data clearly reveal strong effects of relativity and final-state interactions and the importance of two-body meson-exchange currents and isobar configurations. We demonstrate that such effects can be disentangled by extracting these responses using the novel out-of-plane technique.
