Abstract
Spectator nucleon isobar production in pddN* is studied at 0.5-1.0-GeV proton c.m. energy and proposed as a probe of the (NN*) content of the deuteron. The N* spectator distribution from the nucleon pickup mechanism has a maximum at large angles and vanishes at 180°, while the background cross sections of N*' s produced in the elementary pNNN* collision and N*'s from a pion-nucleon exchange mechanism peak at 180° and fall of rapidly. For an estimated NN*(1520) probability of 1.5%, a large-angle cross section of ∼ 0.2μb/sr is obtained.
