We have made a detailed comparison of the charged-particle flow in three-jet events (e/sup +/e/sup -/..-->..qq-barg) and radiative two-jet events (e/sup +/e/sup -/..-->..qq-bar..gamma..) from e/sup +/e/sup -/ annihilation at E/sub c.m./ -- 29 GeV. Accurate comparisons can be made because these two event types have similar topologies. In the angular region between the quark and antiquark jets, we observe substantially fewer charged tracks in the two-jet events than in the radiative three-jet events.
