Title: Measurement of R{sub 10} ({sigma}(W+ > or = to 1 Jet)/{sigma}(W)) at CDF

We present a measurement of the (W + {>=} 1 Jet)/(W Inclusive) cross section ratio, R{sub 10} , in W {yields} e{nu} events for jet ET thresholds ranging from 15 to 95 GeV. Using roughly 100 pb{sup -1} data from the {radical}s = 1.8 TeV p{anti p} collisions at the Fermilab Tevatron Collider, we compare the measured values of R{sub 10} to LO and NLO QCD predictions. Comparisons are made for both 0.4 and 0.7 jet cone clustering. Good agreement between data and theory is observed over a large range of jet E{sub T} thresholds for both cone sizes.
