We report results from Fermilab experiment E769 on the differential cross sections of D charm vector mesons with respect to Feynman-x (xF) and transverse momentum (PT), and on the atomic mass dependence of the production. The D* mesons were produced by a 250 GeV π beam on a target of Be, Al, Cu, and W foils. The dσ/dxF distribution is fit by the form ((1-xF)n) with n=3.5±0.3±0.1, the dσ/dPT2 distribution by exp(-b×PT2) with b=0.70±0.07±0.04 GeV-2, and the cross section A dependence by Aα with α=1.00±0.07±0.02. These results are compared to the equivalent parameters for the production of pseudoscalar D0 and D± charm mesons.
