Abstract: (arXiv)

The cross section for charmed meson production at

\sqrt{s} = 4.03

and 4.14 GeV has been measured with the Beijing Spectrometer. The measurement was made using 22.3

pb^{-1}

of

e^+e^-

data collected at 4.03 GeV and 1.5

pb^{-1}

of

e^+e^-

data collected at 4.14 GeV. Inclusive observed cross sections for the production of charged and neutral D mesons and momentum spectra are presented. Observed cross sections were radiatively corrected to obtain tree level cross sections. Measurements of the total hadronic cross section are obtained from the charmed meson cross section and an extrapolation of results from below the charm threshold.
