“…Its intensity, at the same time, is strongly correlated with that of heavier fragmentation products [29] which suggests a, perhaps partial, interpretation as evaporation from highly excited residual nuclei. For the 197 Au 1 12 C reaction at the same energy, an equilibrium proton component with nearly identical properties was reported by Hauger et al [22].…”

“…Preequilibrium or prebreakup emissions are likely explanations for high-energy components in light-particle spectra [4,10,20,21]. In some cases, the excess kinetic energies have been ascribed to collective flow even though a characteristic proportionality to the fragment mass is not evident in the data [11,22,23]. This situation caused other authors to more generally question the applicability of statistical descriptions for spectator fragmentation [24].…”

Kinetic energies of light fragments A <= 10 from the decay of target spectators in 197Au 197Au collisions at 1000 MeV per nucleon have been measured with high-resolution telescopes at backward angles. Except for protons and apart from the observed evaporation components, the kinetic-energy spectra exhibit slope temperatures of about 17 MeV, independent of the particle species, but not corresponding to the thermal or chemical degrees of freedom at breakup. It is suggested that these slope temperatures may reflect the intrinsic Fermi motion and thus the bulk density of the spectator system at the instant of becoming unstable.

We discuss different aspects which could influence temperatures deduced from experimental isotopic yields in the multifragmentation process. It is shown that fluctuations due to the finite size of the system and distortions due to the decay of hot primary fragments conspire to blur the temperature determination in multifragmentation reactions. These facts suggest that caloric curves obtained through isotope thermometers, which were taken as evidence for a first-order phase transition in nuclear matter, should be investigated very carefully.

Abstract. The leptodermous approximation is applied to nuclear systems for T ¢ 0. The introduction of surface corrections leads to anomalous caloric curves and to negative heat capacities in the liquid-gas coexistence region. Clusterization in the vapor is described by associating surface energy to clusters according to Fisher's formula. The three-dimensional Ising model, a leptodermous system par excellence, does obey rigorously Fisher's scaling up to the critical point. Multifragmentation data from several experiments including the ISiS and EOS Collaborations, as well as compound nucleus fragment emission at much lower energy follow the same scaling, thus providing the strongest evidence yet of liquid-vapor coexistence.
