The PHOBOS experiment at RHIC has measured the charged-particle density dN/d{eta} at mid-rapidity for central Au+Au collisions at center of mass energies of {radical}s{sub NN} = 56, and 130 GeV. We deduce that dN/d{eta} = 408 {+-} 12(stat) {+-}30(syst) and 555 {+-} 12(stat) {+-} 35(syst) for collision energies of 56, and 130, GeV, respectively. These numbers suggest energy densities that are some 70% higher than have been achieved in any heavy-ion collisions previously studied, and also 25-40% higher than nucleon-nucleon collisions at comparable center of mass energies.
