摘要：

Using the CLEO-c detector at the Cornell Electron Storage Ring, we have measured inclusive and exclusive cross sections for the production of D+, D-0 and D-s(+) mesons in e(+)e(-) annihilations at 13 center-of-mass energies between 3.97 and 4.26 GeV. Exclusive cross sections are presented for final states consisting of two charm mesons (D (D) over bar, D*(D) over bar, D*(D) over bar*, Ds+Ds-, D-s*D-+(s)*(-), and D-s*D-+(s)*-) and for processes in which the charm-meson pair is accompanied by a pion. No enhancement in any final state is observed the energy of the Y(4260).
