The Mark II detector at SPEAR has been used to study D-meson production in e/sup +/e/sup -/ annihilation at center-of-mass energies between 3.8 and 6.7 GeV. The neutral and charged D mesons are identified from their K/sup - +/..pi../sup + -/ and K/sup - +/..pi../sup + -/..pi../sup + -/ decay modes. Measurements of R/sub D/ and of the inclusive differential cross section s dsigma/dz are presented. The quasi-two-body cross sections sigma/sub D/D-bar, sigma/sub D/*D-bar, and sigma/sub D/*D-bar * are derived from an overall fit to the D recoil spectra. No evidence was found for the associated production of charmed mesons and charmed baryons.
