Measurement of the Components of the Tensor Analyzing Power in the Reaction γD → ppπ– at Low Proton Energies

Resumo

Results obtained by measuring three components of the tensor analyzing power in the reaction of π- meson photoproduction on deuterons in the range of photon energies 300–800 MeV and proton energies 15–70 MeV are presented. The experiment was performed with an internal tensor-polarized deuterium target at the VEPP-3 electron storage ring, employing the method of recording two protons in coincidence. The obtained measurement results for the tensor analyzing power are compared with theoretical predictions.
