Description
The experimental program of the DEUTERON facility at the VEPP-3 storage ring includes the study of elastic electron-deuteron scattering, the photodisintegration of tensor-polarized deuterons, and the photoproduction of light mesons on deuterons. In this report we discuss recent results from the photodisintegration study. The key feature of the experiment is a Tagging System for almost-real photons, which detects electrons scattered at small angles after interaction with the internal gas target of polarized deuterons. We present experimental results for the T$_{20}$ component of the tensor analyzing power, measured from the target polarization asymmetry in the photodisintegration process at photon energies of 350-680 MeV. In principle, the Tagging System enables the measurement of the T$_{20}$ component at photon energies up to 1600 MeV.
