Abstract
We analyze the coherent electroproduction of neutral pions in nuclei. We find that this process does not contribute to the longitudinal resp onse function for spin saturated nuclei and the dependence of the cros s section on the azimuthal pion angle is particularly simple and given by 1 - epsilon cos 2phi(pi). This angular dependence could be useful to isolate the coherent contribution in future experiments, offering a n advantage over coherent photoproduction. The DELTA-peak is considera bly moved to lower pion energies and appreciably modified due to mediu m corrections.
