Abstract
Identified , , , and transverse momentum spectra at midrapidity in collisions were measured by the PHENIX experiment at RHIC as a function of collision centrality. Average transverse momenta increase with the number of participating nucleons in a similar way for all particle species. Within errors, all midrapidity particle yields per participant are found to be increasing with the number of participating nucleons. There is an indication that , , and yields per participant increase faster than the yields. In central collisions at high transverse momenta , and yields are comparable to the yields.
