The authors propose an observable which will indicate that nuclear matter has undergone a first-order liquid-gas phase transition. That observable is based on the total multiplicity of the fragmenting system (its first derivative) for collisions between heavy nuclei, and is directly accessible by experiments. It maximizes at the same energy as the specific heat, ${C}_{v}$, which typically happens at any first-order phase transition. Other potential indicators of a phase transition are less indicative due to the long-range Coulomb interaction and the fact that the atomic nucleus has a finite size.
