Quantum Interference Effects in N* Electroproduction and Propagation in Nuclei

Abstract

We discuss the unexpected enhancement of the $N^{\ast }$ electroproduction on nuclei recently observed in the $({\gamma }^{\ast },p{\pi }^{-})$ measurement. A mechanism which is able to explain this result is proposed. To clarify the situation, we suggest to perform a new kind of experiment within well specified kinematic conditions.
