Single- and - photoproduction from deuterium has been measured at energies E = 1.7-5.6 GeV and momentum transfers |t| = 0.4-5.6 (GeV/c 2). The ratio / for data taken at E = 3.4 GeV is presented. Also the ratio of the from hydrogen to the from deuterium is extracted to examine the nucleon spectator assumption used in the cross-section ratio analysis. Results are discussed in conjunction with the existing measurements with frameworks ranging from a hadronic description to parton constituent models which successfully characterize the scaling behaviors observed in the exclusive measurements.
