We report results from Fermilab experiment E769 on the differential cross sections of ital Dsup *plus minus charm vector mesons with respect to Feynman-ital x (ital xsub ital F) and transverse momentum (ital Psub ital T), and on the atomic mass dependence of the production. The ital Dsup * mesons were produced by a 250 GeV pi beam on a target of Be, Al, Cu, and W foils. The ital dsigma/ital dxsub ital F distribution is fit by the form (1minusital xsub ital F)sup ital n with ital n=3.5plus minus0.3plus minus0.1, the ital dsigma/ital dPsub ital Tsup 2 distribution by exp(minusital btimesital Psub ital Tsup 2) with ital b=0.70plus minus0.07plus minus0.04 GeVsup minus2, and the cross section ital A dependence by ital Asup alpha with alpha=1.00plus minus0.07plus minus0.02. These results are compared to the equivalent parameters for the production of pseudoscalar ital Dsup 0 and ital Dsup plus minus charm mesons.
