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

   Författare :Anton B Fokin; Partikel- och kärnfysik; []
   Nyckelord :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;

   Sammanfattning : 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.

3. 2. Statistical and Dynamical Aspects of Intermediate Energy Nuclear Collisions

   Författare :Roberta Ghetti; Fysiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; excitation function.; subthreshold pions; pion production; neutron cross-talk; correlation function; interferometry; intermittency; phase transition; thermal scaling; reducibility; multifragmentation; Heavy ion collisions; intermediate energy; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Ghetti;

   Sammanfattning : Studies of intermediate energy heavy ion reactions have revealed the existence of a number of reducibility and thermal scaling properties in nuclear multifragmentation. In particular, the probability of emitting n-fragments is reducible to the probability of emitting a single fragment through the binomial distribution. LÄS MER

5. 4. Ions colliding with Polycyclic Aromatic Hydrocarbons and Fullerenes

   Författare :Fabian Seitz; Henning Schmidt; John Tanis; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

   Sammanfattning : In this thesis a series of experiments on collisions between atomic projectile ions at keV energies and target vapors of either isolated molecules or van der Waals clusters is presented and analyzed. The atomic ions are produced in an Electron Cyclotron Resonance (ECR) ion source, accelerated and guided into the target volume. LÄS MER
