  2. 1. Investigations on Emission Sources in Proton-Nucleus and Nucleus-Nucleus Collisions

    Author : Johan Mårtensson; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; Fysik; Physics; correlation function.; fermion interferometry; t p and d p ratios; target mass dependence; pion angular distribution; pion excitation function; Heavy ion reactions; intermediate energy; cosmic rays; Kosmisk strålning; högenergi;

    Abstract : Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. READ MORE

  4. 2. Net-Charge Fluctuations in Ultra-Relativistic Nucleus-Nucleus Collisions

    Author : Henrik Tydesjö; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quark-Gluon Plasma; Net-Charge Fluctuations; Pad Chamber; högenergi; Kosmisk strålning; High energy interactions; cosmic rays; PHENIX; Heavy-Ion Collisions; RHIC; Fysicumarkivet A:2004:Tydesjö;

    Abstract : PHENIX is one of four experiments at the Relativistic Heavy-Ion Collider, RHIC. The high-energy heavy-ion collisions provided by this accelerator offer the possibility to study nuclear matter at high temperature and density. The high multiplicity of particles produced in these collisions puts high demands on detector performance. READ MORE

  5. 3. Studies of Nuclear Matter under Extreme Conditions: Heavy-Ion Interactions at Ultra-Relativistic Energies

    Author : Joakim Nystrand; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion interactions; quark-gluon plasma; nuclear emulsion; multi-step avalanche chambers; particle production; transverse momentum distributions; intensity interferometry; nucleus-nucleus collisions; rapidity distributions; Physics; Fysik; Fysicumarkivet A:1996:Nystrand;

    Abstract : The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. READ MORE

  6. 4. Experimental Studies of Neutron Emission Induced by Heavy-Ion Scattering

    Author : Pawel Nadel-Turonski; Leif Nilsson; Adriaan van den Berg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; neutron; inelastic scattering; heavy ions; position sensitive silicon detectors; storage ring; cluster-jet target; differential cross section; Kärnfysik; Nuclear physics; Kärnfysik;

    Abstract : A beam of 250A MeV 17O ions was scattered from argon and xenon targets. The large excess of fast neutrons compared with statistical model calculations that was observed earlier for xenon, was confirmed and found for argon as well. READ MORE

  7. 5. On Experimental and Theoretical Studies of Dynamics and Particle Production in p+Nucleus and Heavy Ion Reactions

    Author : Anton B Fokin; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heavy-ion collisions; excitation function; subthreshold pion production; collective effects; entropy and chaos production; d p ratio; molecular dynamics; artificial neural networks; multifragmentation; Physics; Fysik; Fysicumarkivet A:1998:Fokin;

    Abstract : Several experiments and theoretical models of intermediate energy heavy ion collision physics are presented in this thesis. Statistical and dynamical aspects of nuclear collisions are widely discussed these days, particularly in connection with the multifragmentation phenomenon and the possible link to a liquid-gas phase transition in the spinodal region of nuclear matter phase diagram.
