We present a measurement of the top quark pair production cross section in pp collisions at {radical}(s)=1.96 TeV utilizing 425 pb{sup -1} of data collected with the D0 detector at the Fermilab Tevatron Collider. We consider the final state of the top quark pair containing one high-p{sub T} electron or muon and at least four jets. We exploit specific kinematic features of tt events to extract the cross section. For a top quark mass of 175 GeV, we measure {sigma}{sub tt}=6.4{sub -1.2}{sup +1.3}(stat){+-}0.7(syst){+-}0.4(lum) pb, in good agreement with the standard model prediction.
