Energy Dependence of Collective Flow of Neutrons and Charged Particles in 197AU + 197AU Collisions
Collective flow of nuclear matter is one important aspect of the research performed at heavy ion accelerator laboratories. The phenomenon was predicted on the basis of hydrodynamical calculations , and experimental evidence was first presented for the systems 93 Nb + 93 Nb and 197 Au + 197 Au in the projectile energy range between 150 and 1050 MeV/u . The comparison to microscopic calculations shows that nuclear matter is compressed to about two to three times the ground state density and that a substantial fraction of the kinetic energy in the entrance channel is converted into compressional energy . In these calculations, the relation between density and compressional energy depends on the parameterization of the nucleon-nucleon inter-action. The values of its parameters will hopefully be restricted by a comparison of the calculations to experimental data, and thus one can obtain information on the nucleon-nucleon interaction within the nuclear medium which is not accessible from other sources.
