Abstract
We study the \gamma^* N -> \Delta transition amplitudes in a recoil corrected
cloudy bag model approach. A modified Peierls-Thouless projection method is
used to construct the Galilean invariant baryon states. The pionic contribution
is found to be significant. The effect of the recoil correction is to reduce
the magnitude of the transition amplitudes at small momentum transfer and to
enhance them at modest momentum transfers.
