The Beijing Spectrometer (BES) Collaboration has observed exclusive pair production of D_s mesons at the Beijing Electron-Positron Collider (BEPC) at a center-of-mass energy of 4.03 GeV. The D_s mesons are detected in the φπ^+, K¯^(*0)K^+, and K¯^0K^+ decay modes; two fully reconstructed events yield the value (3.9_(-1.9-1.1)^(+5.1+1.8))% for the D_s branching fraction to φπ. This is the first direct, model-independent measurement of this quantity.
