Abstract:
The ratio of π? to π+ electroproduction cross sections from deuterons has been measured in the resonance region at an average four-momentum transfer squared of 0.5 (GeV/c)2. Results are presented over a wide range of pion production angles and comparisons are made with theoretical predictions based on SU(6)w symmetry and the Melosh transformation.
