| Summary: | The transverse electron scattering response function RT of 3He is studied in the quasielastic peak region for momentum transfers between 500 and 700 MeV/c. The calculation is carried out in the active nucleon Breit frame. The response in the laboratory frame is then obtained via a transformation of RT from the active nucleon Breit frame to the laboratory frame. For the current operator one- and two-body parts are taken into account. The one-body current operator includes all leading order relativistic corrections. For the two-body part meson exchange currents consistent with the employed NN potential (Argonne V18) are taken. As three-nucleon force the Urbana IX model is used. In comparison with experiment one finds an excellent agreement of the peak positions. The peak height agrees well with experiment for the lowest considered momentum transfer (500 MeV/c), but tends to be too high for higher momentum transfer (10% at 700 MeV/c). |
