Jet production rates are measured in 
and 
Au collisions at = 200 GeV recorded in 2008 with the PHENIX detector at the Relativistic Heavy Ion Collider. Jets are reconstructed using the 
=0.3 anti-
algorithm from energy deposits in the electromagnetic calorimeter and charged tracks in multiwire proportional chambers, and the jet transverse momentum (
) spectra are corrected for the detector response. Spectra are reported for jets with 
GeV/
within a pseudorapidity acceptance of 
. The nuclear-modification factor (
) values and central-to-peripheral ratios (
) show large, -dependent deviations from unity, challenging the conventional models that relate hard-process rates and soft-particle production in collisions involving nuclei.
