    "abstract": "Polarization observables of the three charge states of the pion for the\n$\\gamma d\\to\\pi NN$ reaction with polarized photon beam and/or oriented\ndeuteron target are evaluated over the whole $\\Delta$(1232)-resonance region\nadopting a nonrelativistic model based on time-ordered perturbation theory.\nResults for the $\\pi$-meson spectra, linear photon asymmetry, vector and tensor\ntarget asymmetries are presented. Particular attention is given, for the first\ntime, to double polarization asymmetries for which we present results for\n$T_{20}^{\\ell}$ and $T_{2\\pm 2}^{\\ell}$. We found that all other double\npolarization asymmetries of photon and deuteron target are vanished.",
