Resumen: A measurement of the cross section for the inclusive production of isolated photons by the CDF experiment at the Fermilab Tevatron collider is presented. The measurement covers the pseudorapidity region |eta(gamma)|< 1.0 and the transverse energy range E-T(gamma)> 30 GeV and is based on 2.5 fb(-1) of integrated luminosity. The sample is almost a factor of 7 larger than those used for recent published results and extends the E-T(gamma) coverage by 100 GeV. The result agrees with next-to-leading order perturbative QCD calculations within uncertainties over the range 50 < E-T(gamma)< 400 GeV, though the energy spectrum in the data shows a steeper slope at lower E-T(gamma).
