Medium Dependence in Heavy Ion Collisions

摘要: One of the proclaimed goals heavy ion collisions with 100 MeV up to 2000 per nucleon is determination equation state nuclear matter, which one needs for example neutron stars, supernova explosions and early universe. But situation in quite different from thermal equilibrium a spherical momentum distribution fixed temperature. The effective nucleon-nucleon interaction as determined by solution Bethe-Goldstone depends through Pauli operator single particle energies on surrounding matter. This dependence especially pronounced since interacting highly dependent: It attractive at small relative momenta repulsive higher values. Thus colhsions matter orbital space. Here results are presented using description reactions intermediate Quantum Molecular Dynamics (QMD) non-relativistic completely covariant (RQMD) form. We show that production gamma-rays, pions inclusive spectra nucleons light nuclei not sensitive states. most observable perpendicular collisions.
