Abstract
The gamma d to d pi 0 process asymmetries for linearly polarized photons Sigma and vector polarized deuterons T were calculated in terms of impulse approximation (IA). The IA is based on the factorization of the isovector gamma N to N pi 0 amplitudes and the deuteron form factors. Several IA versions which include different gamma N to N pi amplitudes, different deuteron wavefunctions and different Fermi momentum choices were used in the calculations. The available experimental data on the asymmetry Sigma can be described in terms of the IA with a certain Fermi momentum choice. The asymmetry T energy and angular dependences are also sensitive to the Fermi momentum choice. Both asymmetries Sigma and T are found to be rather large in the energy range considered, Egamma <800 MeV.
