Popis:	We have obtained 68 +- 9 events of the previously unseen radiative decay eta' ..-->.. ..omega gamma.. (..omega.. ..-->.. ..pi../sup +/..pi../sup -/..pi../sup 0/, ..pi../sup 0/ ..-->.. ..gamma gamma..) in a charged- and neutral-particle spectrometer. Simultaneously, 1505 events of the decay eta' ..-->.. eta..pi../sup +/..pi../sup -/(..nu.. ..-->.. ..gamma gamma..) were collected in the same apparatus, allowing a direct measurement of this branching ratio. We find (eta' ..-->.. ..omega gamma..)/(eta' ..-->.. eta..pi../sup +/..pi../sup -/) = (6.8 +- 1.3) % and use published data to derive (eta' ..-->.. rho..gamma..)/(eta' ..-->.. ..omega gamma..) = 9.9 +- 2.0, in excellent agreement with predictions based on vector meson dominance.
