  We present transverse momentum distributions of charged hadrons produced in
Au+Au collisions at sqrt(s_NN) = 200 GeV. The evolution of the spectra for
transverse momenta p_T from 0.25 to 5GeV/c is studied as a function of
collision centrality over a range from 65 to 344 participating nucleons. We
find a significant change of the spectral shape between proton-antiproton and
peripheral Au+Au collisions. Comparing peripheral to central Au+Au collisions,
we find that the yields at the highest p_T exhibit approximate scaling with the
number of participating nucleons, rather than scaling with the number of binary
collisions.
