Incoherent pion photoproduction on the deuteron is investigated with inclusion of all leading πNN effects.
Formal expressions for polarization observables are derived and described by various beam, target and beam-target asymmetries for polarized photons and/or oriented deuterons.
Results are given for unpolarized cross sections and all possible polarization observables with polarized photons and/or oriented deuterons.
The contributions to the spin asymmetry and the Gerasimov-Drell-Hearn (GDH) integral from separate channels are evaluated by explicit integration up to a photon lab-energy of 350 MeV.
Effects of final-state interaction are investigated and their role in these observables are found to be significant, specially for neutral-pion production.
The extracted results are compared with available experimental data and predictions of other works, and a satisfactory agreement is obtained.
We expect that the results presented in this book may be useful to interpret the recent measurements from the high-intensity and high duty-factor electron accelerators MAMI, ELSA, Jefferson Lab, LEGS, MAX-Lab, SPring-8, LNS, and GRAAL.
