Inclusive Electron Scattering Response Functions of 3He
2011
Theoretical longitudinal and transverse electron scattering response functions are discussed in the quasi-elastic region for momentum transfers q ≥ 500 MeV/c. The response functions are calculated nonrelativistically, however, relativistic corrections to the nucleon one-body charge and current operators are taken into account. The frame dependence of the results is illustrated and it is shown that the so-called active nucleon Breit frame is the most suitable reference frame. In addition we review the results of a two-fragment model, which takes into account the correct relativistic energy of the final hadronic state assuming that a nucleon is knocked out quasi-elastically. New results for the transverse response function are presented at 700 MeV/c ≤ q ≤ 1 GeV/c.
