Abstract
Transverse mass and rapidity distributions for charged pions, charged kaons, protons, and antiprotons are reported for and 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 collisions. The chemical freeze-out temperature appears to be independent of initial conditions at RHIC energies.
