Tensor analyzing power T 20 in the reaction γ d → p n at photon energies 350–680 MeV
We present measurements of the tensor analyzing power $T_{20}$ in the reaction $γ{d}\to pn$ 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 $Θ_p = 70^\circ$-$102^\circ$. 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.
