Investigation of the reaction D(e, pp)e′ π − on a tensorpolarized deuterium target at high proton momenta

The differential cross section of the reaction D(e,pp)e′ π − is measured in the range of proton momenta 300–720 MeV/c and proton emergence angles 64–83° for invariant masses of the pp system ranging from 2m p to 2220 MeV/c 2. The measured values of the cross section are found to differ substantially from single-particle model calculations. The components of the analyzing power for this reaction are measured.
