Abstract
The influence of final-state
NN and
rescattering in
incoherent pion photoproduction on the deuteron has been
investigated. For the elementary photoproduction operator an
effective Lagrangian model is used which describes well the
elementary reaction. The interactions in the final two-body
subsystems are taken in separable form. While
NN rescattering
shows quite a significant effect, particularly strong for neutral
pion production,
rescattering is almost negligible.
Inclusion of such effects leads to an improved and quite
satisfactory agreement with experiment.
