The d(e,e'p) Delta process as an example of quark-exchange currents in leading order

Abstract
It is shown that the off-shell disintegration d to Delta Delta amplitude is determined mainly by quark exchange. So the process d(e,e'p) Delta with Ep being large, Ep>1 GeV, and Delta being practically at rest is in leading order determined by the quark exchange currents. The cross section for this process is only two orders of magnitude less than the cross section for the well known process d(e,e'p)n and could thus, in principle, be measured.
