High-energy photoproduction of /pi//sup +//pi//sup /minus///pi//sup 0/, /ital K//sup +/K/sup /minus//, and /ital pp/bar // states

We report measurements from elastic photoproduction of /omega/'s onhydrogen for photon energies between 60 and 225 GeV, elastic /phi/photoproduction on hydrogen between 35 and 165 GeV and on deuterium between 45and 85 GeV, elastic photoproduction on deuterium of an enhancement at 1.72GeV//ital c//sup 2/ decaying into /ital K//sup +/K/sup /minus//, and elastic andinelastic photoproduction on deuterium of /ital pp/bar // pairs.
