Transverse mass and rapidity distributions for charged pions, charged kaons, protons, and antiprotons are reported for √sNN = 200 GeV pp and Au + Au collisions at Relativistic Heary Ion Collider (RHIC). Chemical and kinetic equilibrium model fits to our data reveal strong radial flow and long duration from chemical to kinetic freeze-out in central Au + Au collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.
