The Reaction D(e,pp)e1π- on Polarized Deuteron at High Proton Momenta

The differential cross section and target asymmetry components of the reaction D(e,pp)e 1π- on polarized deuteron were measured. The kinetic energies of the protons were measured within 55–180 MeV and 46–265 MeV and the acceptance angles in lab. frame are Θ 1,2 = 64° – 82°, Δ o1,2 = 32°. The sharp peak of the tensor a 20-component of the target asymmetry is found near the invariant mass of the ppπ-system M ppπ = 2300 MeV/c 2. The performed calculations of the differential yield and the tensor target asymmetry do not describe the obtained experimental results.
