We present results of a search for W{sup +}W{sup -} production through the leptonic decay channel W{sup +}W{sup -}{r_arrow}l{sup +}l{sup -}{nu}{ovr {nu}} in {ovr p}p collisions at {radical}(s)=1.8TeV. In a 108pb{sup -1} data sample recorded with the Collider Detector at Fermilab, five W{sup +}W{sup -} candidates are found with an expected standard model background of 1.2{plus_minus}0.3 events. The W{sup +}W{sup -} production cross section is measured to be {sigma}({ovr p}p{r_arrow} W{sup +}W{sup -})=10.2{sup +6.3}{sub -5.1}(stat){plus_minus}1.6(syst)pb, in agreement with the standard model prediction. Limits on WW{gamma} and WWZ anomalous couplings are presented. {copyright} {ital 1997} {ital The American Physical Society}
