Jet cross sections have been measured with the ATLAS detector for the first\ntime in proton-proton collisions at center-of-mass energy of t TeV. The\nmeasurement uses an integrated luminosity of 17 nb-1 recorded at the Large\nHadron Collider. The anti-kt algorithm is used to identify jets, with jet\nresolution parameters R=0.6. The dominant uncertainty comes from the jet energy\nscale, which is determined to within 7% for central jets above 60 GeV\ntransverse momentum. Inclusive single-jet differential cross sections are\npresented as functions of jet transverse momentum and rapidity. Dijet cross\nsections are presented as functions of dijet mass and angle chi. The\nexperimental results are compared to the expectations based on next-to-leading\norder QCD.\n
