Study of 3He Nuclei by Polarization Observables in Quasi-Elastic Electron Scattering

Abstract

In a recent set of measurements at Jefferson Laboratory, we have studied the missing-momentum dependence of beam-target asymmetries in exclusive \({\overrightarrow{^3{{\rm He}}}({{\rm e}},{\rm e}'{\rm p}){\rm pn}, \overrightarrow{^3{{\rm He}}}({{\rm e}},{\rm e}'{\rm p}){\rm d} }\), and \({\overrightarrow{^3{{\rm He}}}({{\rm e}},{\rm e}'{\rm d}){\rm p}}\) channels at a previously unattainable level of precision and unreached range in missing momenta. We have also measured single-spin asymmetries in the processes \({\overrightarrow{^3{{\rm He}}}({\vec{{\rm e}}},{\rm e}')}\) and \({\overrightarrow{^3{{\rm He}}}({{\rm \vec{e}}},{\rm e}'{\rm n})}\), where the nuclei were polarized vertically. Preliminary results are presented.
