Quark-exchange versus meson-exchange in d(e,e′p)Δ

We demonstrate that the meson-exchange contribution to d(e,e′p)Δ (Ep ∼ 0.7 − 1 GeV and Δ being at rest) is small compared to the six-quark contribution. The cross-section is large enough to be measured at CEBAF. This means that through this reaction we could observe and study the quark degrees of freedom in the deuteron.
