The [ital WW][gamma] gauge boson couplings were measured using [ital p[bar p]][r arrow]l[nu][gamma]+[ital X] (l=[ital e],[mu]) events at [radical][ital s]=1.8 TeV observed with the D0 detector at the Fermilab Tevatron Collider. The signal, obtained from the data corresponding to an integrated luminosity of 13.8pb[sup [minus]1], agrees well with the standard model prediction. A fit to the photon transverse energy spectrum yields limits at the 95% confidence level on the [ital CP]-conserving anomalous coupling parameters of [minus]1.6[lt][Delta][kappa][lt]1.8 ([lambda]=0) and [minus]0.6[lt][lambda][lt]0.6 ([Delta][kappa]=0). Similar limits are obtained for the [ital CP]-violating coupling parameters.
