Abstract
Coherent pion electroproduction on the deuteron is studied in the
resonance region in the impulse approximation, i.e.,
neglecting pion rescattering and two-body effects. The
elementary reaction on the nucleon is described in the framework
of an effective Lagrangian approach including the dominant
P33(1232) resonance and the usual background terms of the
Born contributions for
production.
We have studied the influence of these different contributions on the
various structure functions which determine the unpolarized
exclusive differential cross section in a variety of kinematic regions.
