We study the effects of the nuclear equation of state (EOS) on intermediate energy heavy-ion collisions using classical microscopic models. The role of the EOS on the disassembly of expanding, hot nuclear matter, as well as the experimental data on multi-fragmentation and collective flow phenomena, are reviewed. Microscopic models used to describe heavy-ion collisions are also discussed. Collisions between cold drops, performed at various energies, are performed using classical molecular dynamics. These drops have an EOS which is similar to that of nuclear matter. Comparisons between collisions and disassemblies of hot, liquid drops indicate that equilibrated, hot matter is formed at 80% of the equilibrium density in central collisions between equal-sized drops. The yield of small clusters is given by the $Asbsp{c}{-tausb{rm eff}}$ power law; $tausb{rm eff}$ depends on the collision energy and has a minimum value of $tausb{rm eff} sim$ 1.7, which is also observed in nuclear fragmentation reactions. Two classical nucleon-nucleon interaction models are developed which have the saturation energy and density of nuclear matter, but have incompressibilities of 250 MeV and 535 MeV. Exact simulations of La+La and Au+Au collisions at 50 to 600 MeV/nucleon indicate that these models are sensitive to the interaction model at $Esb{rm lab} > 400$ MeV/nucleon. The results of Au+Au collisions are also compared to experimental data. The classical nuclear models are used to test the accuracy of the Vlasov-Nordheim approximation in the classical limit, called the Vlasov-Boltzmann (VB) equation, by comparing its results with the exact results at $Esb{rm lab} > 400$ MeV/nucleon. VB is found to be a reasonable approximation when the known EOS and scattering cross sections ($sigmasb{rm eff}$) are used. It is difficult to determine both the EOS and $sigmasb{rm eff}$ by fitting the exact results. A new treatment of scattering in VB simulations, which conserves angular momentum in two-body collisions, is also discussed. Using different n-n and n-p $sigmasb{rm eff}$, the VB simulations give very good agreement with the exact results.

Download Introduction To High-energy Heavy-ion Collisions Book in PDF, ePub and Kindle
Written primarily for researchers and graduate students who are new in this emerging field, this book develops the necessary tools so that readers can follow the latest advances in this subject. Readers are first guided to examine the basic informations on nucleon-nucleon collisions and the use of the nucleus as an arena to study the interaction of one nucleon with another. A good survey of the relation between nucleon-nucleon and nucleus-nucleus collisions provides the proper comparison to study phenomena involving the more exotic quark-gluon plasma. Properties of the quark-gluon plasma and signatures for its detection are discussed to aid future searches and exploration for this exotic matter. Recent experimental findings are summarised.

Download A Short Course on Relativistic Heavy Ion Collisions Book in PDF, ePub and Kindle
Some ideas/concepts in relativistic heavy ion collisions are discussed. To a large extent, the discussions are non-comprehensive and non-rigorous. It is intended for fresh graduate students of Homi Bhabha National Institute, Kolkata Centre, who are intending to pursue career in theoretical /experimental high energy nuclear physics. Comments and criticisms will be appreciated

Download Heavy Ion Collisions At Intermediate Energy: Theoretical Models Book in PDF, ePub and Kindle
Ions are atoms or molecules stripped of their electrons, so they can be accelerated by electric fields. They can be made to hit each other with low energy, intermediate energy, high energy, or very high energy; each energy range seeks to investigate different aspects of hadronic physics. Intermediate-energy heavy ion collisions explore the nuclei far from stability valley, the incompressibility of nuclear matter, the liquid-gas phase transition in nuclear environment, the symmetry energy far from the normal density, and other phenomena. This has been an active field of research for last four decades.This is a book for entrants in the field. It is suitable as a companion book in a graduate course. For practitioners in the field it will be useful as a reference.

Download Comparison of Models of High Energy Heavy Ion Collision. [0. 1 to 2. 0 GeV Book in PDF, ePub and Kindle
Some of the main theoretical developments on heavy ion collisions at energies (0.1 to 2.0) GeV/nuc are reviewed. The fireball, firestreak, hydrodynamic (1-fluid, 2-fluids), ''row on row'', hard sphere and intranuclear cascades, and classical equations of motion models are discussed in detail. Results are compared to each other and to measured Ne + U .-->. p + X reactions.
