We report on a CDF measurement of the total cross section and rapidity distribution, d{sigma}/dy, for q{bar q} {yields} {gamma}*/Z {yields} e{sup +}e{sup -} events in the Z boson mass region (66 < M{sub ee} < 116 GeV/c{sup 2}) produced in p{bar p} collisions at {radical}s = 1.96 TeV with 2.1 fb{sup -1} of integrated luminosity. The measured cross section of 256 {+-} 16 pb and d{sigma}/dy distribution are compared with Next-to-Leading-Order and Next-to-Next-to-Leading-Order QCD theory predictions with CTEQ and MRST parton distribution functions (PDFs). There is good agreement between data and theory except at large rapidity for which further tuning of PDF models may be needed.
