Limits on anomalous WW{gamma} and WWZ couplings are presented from a study of WW/WZ{yields}e{nu}jj events produced in pp(bar sign) collisions at {radical}(s)=1.8 TeV. Results from the analysis of data collected using the DOe detector during the 1993-1995 Tevatron collider run at Fermilab are combined with those of an earlier study from the 1992-1993 run. A fit to the transverse momentum spectrum of the W boson yields direct limits on anomalous WW{gamma} and WWZ couplings. With the assumption that the WW{gamma} and WWZ couplings are equal, we obtain -0.34<{lambda}<0.36 (with {delta}{kappa}=0) and -0.43<{delta}{kappa}<0.59 (with {lambda}=0) at the 95% confidence level for a form-factor scale {lambda}=2.0 TeV.
