  1. 21. Two photon above threshold ionization in a relativistic framework : Attosecond delays in high Z elements

    Författare :Jimmy Vinbladh; Eva Lindroth; Patrick Norman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Recent advances in experimental physics opens up for improved time resolution on measurements of ionizing processes in atoms caused by an EM-field. There exist non-relativistic models that describe photo-ionization events involving two photons, for various atoms, where relativistic effects, e.g. spin-orbit interactions, are small. LÄS MER

  3. 22. Net-Charge Fluctuations in Ultra-Relativistic Nucleus-Nucleus Collisions

    Författare :Henrik Tydesjö; Partikel- och kärnfysik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
