Identified Π^+/−,K^+/−,p and p transverse momentum spectra at mid-rapidity in √_^sNN = 130 GeV Au-Au collisions were measured by the PHENIX experiment at RHIC as a function of collision centrality. Average transverse mome nta increase with the number of participating nucleons in a similar way for all particle species. Within errors, all mid-rapidity particle yields per participant are found to be increasing with the number of participating nucleons. There is an indication that K^+/−,p and p yields per participant increase faster than the Π^+/−yields. In central collisions at high transverse momenta (pT≥ 2 GeV/c),p and p yields are comparable to the Π^+/−y ields.
