Abstract
Transverse momentum spectra for charged hadrons and for neutral pions in the range have been measured by the PHENIX experiment at RHIC in collisions at . At high the spectra from peripheral nuclear collisions are consistent with scaling the spectra from collisions by the average number of binary nucleon-nucleon collisions. The spectra from central collisions are significantly suppressed when compared to the binary-scaled expectation, and also when compared to similarly binary-scaled peripheral collisions, indicating a novel nuclear-medium effect in central nuclear collisions at RHIC energies.
