Abstract
J.Phys. G31 (2005) 105-118 Spin observables for the three charge states of the pion for the pion
photoproduction reaction on the deuteron, $\gamma d\to\pi NN$, with polarized
photon beam and/or oriented deuteron target are predicted. For the beam-target
double-spin asymmetries, it is found that only the longitudinal asymmetries
$T_{20}^{\ell}$ and $T_{2\pm 2}^{\ell}$ do not vanish, whereas all the circular
and the other longitudinal asymmetries do vanish. The sensitivity of spin
observables to the model deuteron wave function is investigated. It has been
found that only $T_{21}$ and $T_{22}$ are sensitive to the model deuteron wave
function, in particular in the case of $\pi^0$-production above the
$\Delta$-region, and that other asymmetries are not.
