Interference Effects in Relativistic Deuteron Electrodisintegration

We extend the relativistic plane--wave impulse approximation formalism to incorporate a specific class of relativistic interference effects for use in describing inclusive electrodisintegration of $^2$H. The role of these ``exchange'' terms for the various response functions accessible in parity--conserving and --violating inclusive processes is investigated and shown, especially for the latter, to have important consequences for experiment. An extension to a simple quasi--deuteron model is also considered.
