Total and partial γd, γp and γn reactions were studied in the SLAC 82 inch deuterium-filled bubble chamber, which was exposed to a linearly polarized photon beam at an energy of 7.5 GeV. We report total, topological and channel cross sections for these reactions. The γn average charge multiplicity was found to be one unit of charge less than the γp average charge multiplicity. The isoscolar-isovector interference term as calculated by comparing the γp charge symmetric reactions is found to be small.

The asymmetry of the reaction γ d π − p ( p S ) with linearly polarized photons has been measured at 3.4 GeV and momentum transfers √− t between 0.2 and 0.8 GeV/ c . As in π + production, the asymmetry is large and positive at small momentum transfers but drops rapidly with increasing √− t , crossing zero around √− t = 0.55 GeV/ c .
