π±ΔElectroproduction in the Electric Born Model

The electric Born model for ${\pi }^{\pm }\Delta$ photoproduction is extended to electroproduction, allowing for different electric form factors for the participating particles. A comparison with recent small-angle ${\pi }^{-}{\Delta }^{++}$ and ${\pi }^{+}{\Delta }^0$ electroproduction data is made. The longitudinal cross section is larger than the transverse cross section, although its predominance is less pronounced than in ${\pi }^{+}n$ electroproduction. The model is also used to describe the reaction ${\pi }^{+}p\to {\rho }^0{\Delta }^{++}$.
