ON THE ELECTROMAGNETIC PRODUCTION OF THE PROPOSED PI-NN RESONANCE D'

We examine the electromagnetic decay rates as well as the photo- and e lectroproduction cross sections of the proposed pi NN resonance d', fo r the existence of which evidence has been claimed in the pionic doubl e charge exchange (DCX) on nuclei as well as in the 2 pi-production in pp-collisions. Based on the d' parameters deduced from DCX, we estima te the d'-production on the deuteron in the reactions gamma d --> NN p i and ed --> e'NN pi. Comparing to the non-resonant cross sections at the relevant energies and momentum transfers, we discuss the feasibili ty of a search for a d' signal both in gamma d --> np pi(0) and in ed --> e'NN pi.
