A sample of 475 events, in which two charmed-particle decays are observed, is analyzed to determine distributions of two-particle kinematic variables. One charmed particle with x(F) > 0 is fully reconstructed and the other is at least partially recontructed. The distributions of Delta phi and p(T)(2) are compared with a next-to-leading order QCD calculation.
