We present a measurement of the top pair production cross
section in p anti-p collisions at s**(1/2) = 1.96 TeV. We collect a data
sample with an integrated luminosity of 194 +/- 11 pb-1 with the CDF II
detector at the Fermilab Tevatron. We use an artificial neural network
technique to discriminate between top pair production and background
processes in a sample of 519 lepton+jets events, which have one isolated
energetic charged lepton, large missing transverse energy and at least
three energetic jets. We measure the top pair production cross section
to be sigma_tt-bar = 6.6 +/- 1.1 +/- 1.5 pb, where the first uncertainty
is statistical and the second is systematic.
