Results of the Jefferson Lab Hall A quasielastic 3He(e,e′p)pn measurements are presented. These measurements were performed at fixed transferred momentum and energy, q=1502 MeV/c and ω=840 MeV, respectively, for missing momenta pm up to 1 GeV/c and missing energies in the continuum region, up to pion threshold; this kinematic coverage is much more extensive than that of any previous experiment. The cross section data are presented along with the effective momentum density distribution and compared to theoretical models.
