This thesis reports on data taken in experiment E369 using the Chicago Cyclotron Spectrometer at Fermilab. A search for charmed D mesons was made using a beam of 217 GeV/sup ..pi../sup -// incident on a liquid hydrogen target. The trigger required a recoil proton and a prompt muon. A total of 50 +- 12 charged D events were seen in the K/sup + -/..pi../sup - +/..pi../sup - +/ channels and were split between the two channels in about equal amounts. Cuts were made which selected diffractive events, but when these cuts were removed the signal remained the same although the background was greatly increased. The Feynman x and angular distributions were consistent with diffractive production. A diffractive model yields a cross section of (6 - 10) + 4 ..mu..b.
