Abstract

The thermal component of the 8GeV/c π+Au data of the ISiS Collaboration is shown to follow the scaling predicted by Fisher’s model when Coulomb energy is taken into account. Critical exponents τ and σ, the critical point (pc,ρc,Tc), surface energy coefficient c0, enthalpy of evaporation ΔH, and critical compressibility factor CcF are determined. For the first time, the experimental phase diagrams, (p,T) and (T,ρ), describing the liquid vapor coexistence of finite neutral nuclear matter have been constructed.
