摘要: Recent heavy ion reaction studies aimed at elucidating the properties of low density matter produced in near Fermi-energies are discussed. At lowest densities and temperatures large alpha mass fractions observed. The symmetry free energies derived from isoscaling analyses far above those obtained common effective interaction calculations, reflecting cluster formation, primarily particles, not included such calculations. Theoretical modeling these results requires consideration formation medium modifications properties.
