Abstract

We present measurements of the tensor analyzing power $T_{20}$ in the reaction $γ d \to p n$ at photon energies $E_{γ} = 350$ - $680$ ~MeV. The experiment was performed at the VEPP-3 storage ring using an internal tensor-polarized deuterium gas target and a tagged quasi-real photon beam. The data were obtained for proton emission angles $Θ_{p} = 7 0^{\circ}$ - $10 2^{\circ}$ . Comparison with modern meson-baryon calculations shows generally satisfactory agreement within the present uncertainties. A theoretical analysis of an extended data set, covering the energy range from threshold to 680~MeV and including both the new data and the previous results from 2007, is presented.
