Results are presented of a measurement of the production of D*+ (D*-) in 250-GeV/c -N interactions. We observe 2.17.8 events corresponding to a charge-D* cross section (D*) of 0.41.5 b/nucleon. When averaged with our previous measurement made at 200 GeV/c, the result is (D*)=2.31.0 b/nucleon with (d/dx)-x=0=4.62.0 b. 1986 The American Physical Society.
