  1. 1. High-sensitivity Radioactive Xenon Monitoring and High-accuracy Neutron-proton Scattering Measurements

    Författare :Cecilia Johansson; Jan Blomgren; Nils Olsson; Allena Opper; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; Monte Carlo simulations; MCNP; xenon detection; detector response; neutron detection; elastic scattering; differential cross section; Kärnfysik; Nuclear physics; Kärnfysik;

    Sammanfattning : Two aspects of applied nuclear physics have been studied in this thesis; Monte Carlo simulations for high-sensitivity monitoring of radioactive xenon and high-accuracy neutron-proton scattering measurements for neutron physics applications and fundamental physics. The Monte Carlo simulations have been performed for two systems for detection of radioactive xenon, using the MCNP code. LÄS MER

  3. 2. Ultra-fast dynamics in atoms and molecules during photoionization: from attoseconds to femtoseconds

    Författare :Erik Månsson; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectroscopy; momentum imaging; coincident detection; correlation; direct double ionization; Born–Oppenheimer approximation; high harmonics; synchrotron radiation; Fysicumarkivet A:2014:Månsson;

    Sammanfattning : Treating the correlated behaviour of multiple particles is challenging for both theory and experiment. This thesis reports on a variety of experimental investigations aiming to advance the understanding of fundamental processes in atoms and molecules: double ionization, isomerization and dissociation.
