Measurements are presented of the properties of high transverse momentum jets, produced in protonproton collisions at a center-of-mass energy o 7 TeV. The data correspond to an integrated luminosity of 35 pb
1 and were collected with the ATLAS detector in 2010. Jet mass, width, eccentricity, planar flow and angularity are measured for jets reconstructed using the anti-kt algorithm with distance parameters R ¼ 0:6 and 1.0, with transverse momentum pT > 300 GeV and pseudorapidity j
j < 2. The measurements are compared to the expectations of Monte Carlo generators that match leading-logarithmic parton showers to leading-order, or next-to-leading-order, matrix elements. The generators describe the general features of the jets, although discrepancies are observed in some distributions.
