This thesis presents results derived from data collected by Fermilab experiment E743. LEBC, a small, rapid cycling, liquid hydrogen bubble chamber coupled with the FMPS a conventional spectrometer with particle identification, was exposed to an 800-GeV proton beam. The sample of data described in this thesis corresponds to a total accumulated statistics equivalent to a sensitivity of 9.0 {plus minus} 1.0 events/{mu}b. This thesis studies the inclusive production properties of D/D mesons and the {phi}{sub T} angular correlation of DD pairs. The total cross section {sigma} (D/D) is 62{sub {minus}10}{sup +13} {mu}b. The differential cross section parametrized by the empirical formula d{sup 2}{sigma}(D/D)/dx{sub F}dp{sup 2}{sub T} {approx} (1 - {vert bar}x{sub F}{vert bar}){sup n}e{sup {minus}}bpT{sup 2} yields n = 8.8{sub {minus}}{sup 1.8+2.1} and b = 0.79{sub {minus}0.15}{sup +0.17} (GeV/c){sup 2}. The measurement of {phi}{sub T} yields ({phi}{sub T}) = 115 {plus minus} 29 degrees. The comparison of these results to fusion model calculations results in good agreement.
