abstract = "A study of W+W- events accompanied by hard photon radiation produced in e(+)e(-) collisions at LEP is presented. Events consistent with two on-shell W-bosons and an isolated photon are selected from 183 pb(-1) of data recorded at root s = 189 GeV. From these data, 17 W+W- gamma candidates are selected with photon energy greater than 10 GeV, consistent with the Standard Model expectation. These events are used to measure the e(+)e(-) --> W+W- gamma cross-section within a set of geometric and kinematic cuts, <(sigma)over cap>(WW gamma) = 136 +/- 37 +/- 8 fb, where the first error is statistical and the second systematic.
