The intermediate p T region (2–5 GeV/ c ) in central Au+Au collisions at RHIC has a rich physics content. The (anti)proton to pion ratio at the intermediate p T gives us a powerful tool to investigate the bulk properties of the hot and dense matter created at RHIC and their hadronization processes. We present the preliminary results of identified charged hadron spectra at the lower beam energies at RHIC. The excitation function of (anti)proton to pion ratios from SPS to RHIC is shown. We also discuss the onset of the baryon enhancement at the high energy heavy ion collisions.
