The transverse momentum and total cross section of e{sup +}e{sup -} pairs in the Z -boson region of 66<M{sub ee}<116 GeV /c{sup 2} from pp collisions at {radical}(s)=1.8 TeV are measured using 110 pb{sup -1} of collisions taken by the Collider Detector at Fermilab during 1992-1995. The total cross section is measured to be 248{+-}11 pb . The differential transverse momentum cross section is compared with calculations that match quantum chromodynamics perturbation theory at high transverse momentum with the gluon resummation formalism at low transverse momentum.
