抄録

We report differential cross sections for the production of D*^±(2010) produced in 500 GeV/c π^--nucleon interactions from experiment E791 at Fermilab, as functions of Feynman-χ (χ_F) and transverse momentum squared (p_T²). We also report the D*^± charge asymmetry and spin-density matrix elements as functions of these variables. Investigation of the spin-density matrix elements shows no evidence of polarization. The average values of the spin alignment are (η) = 0.01 ± 0.02 and -0.01 ± 0.02 for leading and non-leading particles, respectively.
