Measurement of Tensor Analyzing Power Components of the γd→pnπ0 Reaction

Abstract

The results of measurements of three tensor analyzing power components of the reaction of incoherent photoproduction of a π⁰-meson on a deuteron in the ranges of proton and neutron energies, 15–200 and 15–150 MeV, respectively, are presented. The experiment is performed on an internal tensor-polarized gaseous deuterium target of a VEPP-3 electron storage ring using the method of proton and neutron coincidence counting. The results of measurements of tensor analyzing power components are compared with those obtained by statistical modeling performed within a theoretical model.
