An exclusive study of the interaction of 1A GeV Au with C shows a separability into two stages: a prompt stage involving emission of most z = 1 and some Z = 2 particles and a second stage involving the decay of an equilibrated remnant, which typically undergoes multifragmentation. The mean mass, charge, excitation energy, and the initial temperature Ti of the remnant have been determined as a function of the total charge multiplicity, m, as has the freeze-out temperature Tf. Both Ti and Tf increase linearly with m and their values at the critical point have been determined. Tf rises monotonically with excitation energy as expected for a continuous phase transition.
