  2. 32. Autoionizing states and their relevance in electron-ion recombination

    Författare :Dragan Nikolić; Eva Lindroth; Gleb Gribakin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron-ion recombination; Autoionization; Electron correlation calculations; Doubly excited states; Relativistic many-body perturbation theory; Coupled-cluster methodology; Intruder state problem; Physics; Fysik;

    Sammanfattning : Atomic physics plays an important role in determining the evolution stages in a wide range of laboratory and cosmic plasmas. Therefore, the main contribution to our ability to model, infer and control plasma sources is the knowledge of underlying atomic processes. LÄS MER

  3. 33. Ion escape from Mars

    Författare :Qi Zhang; Mats Holmström; Xiao-Dong Wang; Shahab Fatemi; Hans Nilsson; David Andrews; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : When the solar wind reaches the Mars obstacle, mass loading by planetary ions slows down the solar wind and raises the bow shock. The Martian atmosphere is undergoing the a scavenging by the solar wind without the protection of a global magnetic field. Atmospheric escape is an important process for the evolution of the Martian climate. LÄS MER

  4. 34. Hadronic Interactions at High and Low Energies

    Författare :Marius Utheim; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QCD; Phenomenology; Hadronic rescattering; Heavy ions; Exotic hadrons; Cosmic rays;

    Sammanfattning : In the past, development of the PYTHIA event generator has mainly concentrated on the physics of proton–proton collisions at high energies, as this is the most important case to modern high energy physics experiments. However, there are situations where more generic beam configurations are relevant. LÄS MER

  5. 35. Radiation and matter: how do they play with each other?

    Författare :Davide Mancusi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy ions; models; transport codes; Boltzmann equation; Monte Carlo; radioprotection in space; radiotherapy; nuclear reactions;

    Sammanfattning : The propagation of radiation is affected by the presence of matter; at the same time, the physicochemical properties of matter are modified by the passage of radiation. The interplay of radiation and matter is of crucial importance in many modern applications: accelerated heavy ions, in particular, can be used in radiotherapeutical treatments of some cancers; moreover, they are present in the space radiation environment and represent a serious threat to the health of spaceship crews and to the functionality of electronic equipment on board.
