Abstract
We report results from a preliminary analysis of approximately 30 million reconstructed events (30% of the data) from E-691, a charm photoproduction experiment conducted at the Fermilab Tagged Photon Laboratory in 1985. We present ratios of antiparticles to particles, p/sub T//sup 2/ distributions, x/sub F/ distributions, the total charm production cross-section and its energy dependence and the fraction of D/sup 0/s from D*s.
