We report on a search for pair production of first-generation
scalar leptoquarks (LQ) in p anti-p collisions at s**(1/2) = 1.96 TeV using an
integrated luminosity of 200 pb-1 collected at the Fermilab Tevatron
collider by the CDF experiment. We observe no evidence for LQ production in
the topologies arising from LQ overline{LQ} --> eqeq and LQ overline{LQ} -->
eq nuq, and derive 95% C.L. upper limits on the LQ production cross section.
The results are combined with those obtained from a separately reported CDF
search in the topology arising from LQ L-Q --> nu q nu q and 95% C.L. lower
limits on the LQ mass as a function of beta = BR(LQ --> eq) are derived. The
limits are 236, 205 and 145 GeV/c2 for beta = 1, beta = 0.5 and beta = 0.1,
respectively.
