We have made measurements of decay modes of neutral {ital D} mesons into exclusive final states containing photons using data collected with the CLEO detector at the Cornell Electron Storage Ring. We report observation of {ital D}{sup 0}{r arrow}{ital K}{sup {minus}}{pi}{sup +}{pi}{sup {minus}}{pi}{sup +}{pi}{sup 0} (charge conjugates are implicit), and present new measurements of the branching ratios for {ital D}{sup 0}{r arrow}{ital K}{sup {minus}}{pi}{sup +}{pi}{sup 0}, {ital D}{sup 0}{r arrow}{ital {bar K}}{sup 0}{pi}{sup +}{pi}{sup 0}{pi}{sup {minus}}, {ital D}{sup 0}{r arrow}{ital {bar K}}{sup 0}{pi}{sup 0}, {ital {bar K}}{sup *0}{eta}, and {ital D}{sup 0}{r arrow}{ital {bar K}}{sup 0}{omega}. Where possible, results are compared with theoretical predictions for two-body {ital D}{sup 0} decays.
