The thermal component of the 8 GeV/c pi+ 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 tau and sigma, the critical point (p(c),rho(c),T(c)), surface energy coefficient c(0), enthalpy of evaporation DeltaH, and critical compressibility factor C(F)(c) are determined. For the first time, the experimental phase diagrams, (p,T) and (T,rho), describing the liquid vapor coexistence of finite neutral nuclear matter have been constructed.

We explore the natural limit of binomial reducibility in nuclear multifragmentation by constructing excitation functions for intermediate mass fragments (IMF) of a given element Z. The resulting multiplicity distributions for each window of transverse energy are Poissonian. Thermal scaling is observed in the linear Arrhenius plots made from the average multiplicity of each element. "Emission barriers" are extracted from the slopes of the Arrhenius plots and their possible origin is discussed.

The production of %e, Li, ^Be, ^Be, B, C, N, O, and F has been studied in the reaction 90-MeV %e+ "^^Ag. Although the yields of the heavier elements are orders of magnitude less than for %e, the energy spectra, charge, and angular distributions indicate that an equilibrium statistical process is responsible for the production of these heavy nuclei in the backward hemisphere.
