An analysis of high-transverse-momentum electrons using data from the Collider Detector at Fermilab (CDF) of {ital {bar p}p} collisions at {radical}{ital s} =1800 GeV yields values of the production cross section times branching ratio for {ital W} and {ital Z}{sup 0} bosons of {sigma}({ital {bar p}p}{r arrow}{ital WX}{r arrow}{ital e}{nu}{ital X})=2.19{plus minus}0.04(stat){plus minus}0.21(syst) nb and {sigma}({ital {bar p}p}{r arrow}{ital Z}{sup 0}{ital X}{r arrow}{ital e}{sup +}{ital e{minus}}{ital X})=0.209{plus minus}0.013(stat) {plus minus}0.017(syst) nb. Detailed descriptions of the CDF electron identification, background, efficiency, and acceptance are included. Theoretical predictions of the cross sections that include a mass for the top quark larger than the {ital W} mass, current values of the {ital W} and {ital Z}{sup 0} masses, and higher-order QCD corrections are in good agreement with these measured values.
