11. Resonant phenomena in atomic collisions : a study of analytic properties of a non-relativistic scattering formulation
Sammanfattning : .... LÄS MER
12. Collision- and photon-induced dynamics of complex molecular ions in the gas phase
Sammanfattning : In this thesis, I report experiments probing collision- and photon-induced molecular dynamics in the gas phase. Excited molecules formed in such interactions may relax by emitting electrons or photons, isomerization or fragmentation. LÄS MER
13. Net-Charge Fluctuations in Ultra-Relativistic Nucleus-Nucleus Collisions
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
14. Statistical and Dynamical Aspects of Intermediate Energy Nuclear Collisions
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
15. From Strange to Charm : Meson production in electron-positron collisions
Sammanfattning : Decays of pseudoscalar mesons into a lepton-antilepton pair are very rare within the Standard Model since they cannot proceed via a single photon process. The C-even neutral mesons can be produced in electron-positron collisions by a two-photon intermediate state. LÄS MER
