Medium energy collisions of heavy nuclei in the three-dimensional nuclear fluid dynamical-(NFD) and time-dependent Hartree-Fock (TDHF) models

We study heavy ion collisions at bombarding energies of Esub(LAB)/n approx. 20-200 MeV within the three-dimensional NFD- and TDHF-models. A surprisingly good agreement between the results of the different models is found: The comparison phenomena occuring at these bombarding energies are quantitatively similar as a function of the bombarding energy as well as for various impact parameters. The formation of abnormal superdense nuclear matter ('density isomers') is investigated in a schematic model for the nuclear equation of state. Again we find very similar results in the two models. Density isomers can be formed in high energy heavy ion collisions above a critical bombarding energy and below a critical impact parameter, which both depend on the details of the nuclear equation of state. Cross sections for the formation of density isomers are presented. An experiment for the detection of abnormal nuclear matter in fast, central heavy ion collisions is proposed.
