Title: Asymmetry dependence of the caloric curve for mononuclei

Abstract

The asymmetry dependence of the caloric curve, for mononuclear configurations, is studied as a function of neutron-to-proton asymmetry with a model that allows for independent variation of the neutron and proton surface diffusenesses. The evolution of the effective mass with density and excitation is included in a schematic fashion and the entropies are extracted in a local density approximation. The plateau in the caloric curve displays only a slight sensitivity to the asymmetry.

  • The A/Z dependence of projectile fragmentation at relativistic energies has been studied with the ALADIN forward spectrometer at SIS. A stable beam of {sup 124}Sn and radioactive beams of {sup 124}La and {sup 107}Sn at 600 MeV per nucleon have been used in order to explore a wide range of isotopic compositions. Chemical freeze-out temperatures are found to be nearly invariant with respect to the A/Z of the produced spectator sources, consistent with predictions for expanded systems. Small Coulomb effects ({delta}T{approx_equal}0.6 MeV) appear for residue production near the onset of multifragmentation.
  • In a finite temperature Thomas-Fermi theory with realistic nuclear interactions, we construct caloric curves for finite nuclei enclosed in a sphere of about 4 to 8 times the normal nuclear volume. The specific heat capacity C{sub v} shows a peaked structure that is possibly indicative of a liquid-gas phase transition in finite nuclear systems. {copyright} {ital 1997} {ital The American Physical Society}
  • In a finite temperature Thomas-Fermi theory, we construct caloric curves for finite nuclei enclosed in a freeze-out volume a few times the normal nuclear volume, with and without inclusion of flow. Without flow the caloric curve indicates a smooth liquid-gas phase transition, whereas with flow the transition may be very sharp. We discuss these results in the context of two recent experiments, one for a heavy symmetric system (Au+Au at 600A MeV ) and the other for a highly asymmetric system (Au+C at 1A GeV ) where different behaviors in the caloric curves are seen. {copyright} {ital 1997} {ital Themore » American Physical Society}« less
