摘要：
Coherent photoproduction of pi(0)-meson from the deuteron near pi(0)-production threshold is investigated with special emphasize on single polarization observables. We report numerical results for the linear photon asymmetry Sigma and tensor deuteron spin asymmetries T-2M (M=0,1,2). The sensitivity of obtained results to the D-state contribution in the deuteron wave function of realistic NN potentials is studied. It is shown that the influence of D-state contribution on the predicted spin observables is sizable, and it provides important constraints for the extraction of the elementary neutron amplitude. Compared with the experimental data from TAPS collaboration for differential cross section, we obtain a satisfactory agreement.
