Abstract

The proton momentum distribution of ${}^{3}{He}$ has been determined up to momenta of 310 MeV/c by use of the reaction ${}^{3}{He} (e, e^{'} p)$ . The experimental missing-energy resolution, $δ E_{m} = 1.2$ MeV, was sufficient to separate the two- and three-body breakup channels. Results for the three-body disintegration have been obtained up to missing-energy values of 80 MeV. The resulting spectral function is compared to the predictions of Faddeev and variational calculations.
