  2. 16. Calculations on the possibilities for photoionization-delay studies with circularly polarized light

    Author : Johanna Sörngård; Eva Lindroth; Markus Kowalewski; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attosecond physics; photoionization delay; circular polarization; Theoretical Physics; teoretisk fysik;

    Abstract : Advances in experimental physics, specifically light sources emitting at an attosecond time scale, has enabled the time resolution of atomic processes like photoionization. Recent developments have allowed these sources to produce light with non-linear polarization. READ MORE

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

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

    Abstract : 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.

  7. 20. From source to the environment : Strategies for identification and determination of hydroxylated polycyclic aromatic hydrocarbons in complex particulate matrices

    Author : Rozanna Avagyan; Roger Westerholm; Conny Östman; Marja-Liisa Riekkola; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; OH-PAHs; hydroxy-PAHs; particulate matter; PM; airborne particles; combustion particles; wood combustion; suspect screening; non-target screening; high resolution mass spectrometry; HRMS; atmospheric pressure photoionization; APPI; Analytical Chemistry; analytisk kemi;

    Abstract : Adverse health effects have been linked to exposure to particulate matter, and wood combustion is considered as an important source of harmful particulate matter in the urban air and environment. Hydroxylated polycyclic aromatic hydrocarbons are a group of compounds with toxic, endocrine disrupting and carcinogenic properties. READ MORE
