The spectrum of photoprotons produced by 500-Mev bremsstrahlung on hydrogen and deuterium has been measured at laboratory angles of 29.7 deg , 41.2 deg , and 51.8 deg with a telescope of three scintillation coumters. From the hydrogen data the pi /sup 0/ cross section of hydrogen was obtained, which agrees with the previous results of this laboratory. The contribution of the deuterium photodisintegration reaction was subtracted from the deuterium counting rate amd the deuterium-to-hydrogen ratio of recoil protons from meson photoproduction was obtained. This ratio was also calculated from the deuterium pi /sup -/ and hydrogeu pi /sup 0/ photoproduction cross sections, by means of the''spectator model'' of the deuteron. In this model photons interact with only one of the deuterium nucleons and the initial momentum of the target nucleon is taken into account. The ratio predicted by this model is significantly larger than the experimental ratio. (auth)
