Quasifree (e, e′p) Reaction onHe3

Abstract

The proton momentum distribution of ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ has been determined up to momenta of 310 MeV/c by use of the reaction ${}_{}{}^3{}_{}{}^{}\mathrm{He}(e, e^{\prime }p)$. The experimental missing-energy resolution, $\delta E_m=1.2\mathrm{}$ 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.
