We report on the measurement of the rapi+dity distribution,
d sigma/dy, over the full kinematic range for e+ e- pairs produced in p
anti-p collisions at s**(1/2) = 1.96 TeV in the Z boson region of 66 <
M_ee < 116 GeV/c2. The data sample consists of 1.1 fb-1 of p anti-p
collisions at sqrt s = 1.96 TeV taken by the Collider Detector at Fermilab
(CDF). The d sigma/ dy is compared with the NLO theory prediction.
