Abstract
First results on inclusive D-0 and D-*+/- production in neutral current deep inelastic ep scattering are reported using data collected by the H1 experiment at HERA in 1994. Differential cross sections are presented for both channels and are found to agree well with QCD predictions based on the boson gluon fusion process. A charm production cross section for 10 GeV2 less than or equal to Q(2) less than or equal to 100 GeV2 and 0.01 less than or equal to y less than or equal to 0.7 of sigma (ep --> <ec(c)over bar X>) = (17.4 +/- 1.6 +/- 1.7 +/- 1.4) nb is derived. A first measurement of the charm contribution F(2)(<c(c)over bar>) (x, Q(2)) to the proton structure function for Bjorken x between 8 . 10(-4) and 8 . 10(-3) is presented. In this kinematic range a ratio F(2)(<c(c)over bar>)/F-2 = 0.237 +/- 0.021 +/- 0.041 is observed.
