An investigation of the ( gamma , d) reaction in sulfur, cobalt, and copper was made. Bremsstrahlung of 30-Mev maximum energy was used. The emitted charged photoparticles were deflected by a magnetic field and recorded in nuclear emulsions. The range and the orientation of the tracks in the emulsions were measured and the trajectories of the photoparticles were calculated backwards for protons, deuterons, and alpha particles. The intersection point of each trajectory with the target plane gave information about the kind of photoparticle that produces the track. The ratio R/sub dp/ between the ( gamma , d) yield and the ( gamma , p) yield was determined. No strong fluctuation in the ratio between the adjacent elements cobalt and copper was observed. The ratios found were all zero for the three elements sulfur, cobalt, and copper, with a standard deviation of 0.009, 0.012 and 0.018, respectively. A calculation based on the statistical model of the ratio R/sub dp/ was made. The ratios obtained are, within the limits of the errors, in agreement with the experimental results. (auth)
