Abstract

Tensor analyzing-power components [Formula: see text], [Formula: see text], and [Formula: see text] for the reaction [Formula: see text] have been studied for the first time in the photon energy range from 280 to 500 MeV. The data are extracted from the experimental statistics accumulated at the VEPP-3 storage ring in 2002-2003. The measured asymmetries are compared with the results of statistical simulations performed with the [Formula: see text] amplitude from a spectator model, taking into account corrections for the final-state interaction. The comparison demonstrates quite good agreement between the experimental results and the theory.
