1. 6. High-Order Harmonics- Characterisation, Optimisation and Applications

   Författare :Claire Lyngå; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high-harmonic generation; VUV spectroscopy; high-power lasers; Atomic and molecular physics; radiative lifetimes; XUV spectroscopy; Atom- och molekylärfysik; Fysicumarkivet A:1999:Lyngå;

   Sammanfattning : Recent advances in laser technology, with the development of extremely short-pulse, high-intensity lasers, have opened doors to new areas in atomic physics. By focusing light from an intense, short-pulse laser into a gas jet, the emission of high-order harmonics of the laser frequency has been studied. LÄS MER

5. 9. Laboratory and Stellar Spectra in High Resolution: Studies of Fe, Pt and Tl in Peculiar Stars

   Författare :Gabriele Kalus; Fysiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; high-resolution spectroscopy; hyperfine structure; peculiar stars; iron; platinum; lead; upsilon Sagittarii; HR7775; chi Lupi; isotope shift; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1997:Kalus;

   Sammanfattning : The near-infrared spectrum of upsilon Sagittarii has been registered using the SOFIN high resolution spectrometer on the Nordic Optic Telescope, La Palma. For the first time 4f-5g transitions of Fe II in any astrophysical spectrum have been identified. LÄS MER

7. 10. Experimental Techniques for Studies in Atomic & Molecular Physics

   Författare :Filip Heijkenskjöld; Jan-Erik Rubensson; Peder Royen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; fast ion beam laser spectroscopy; time of flight photoelectron photoelectron coincidence; hyperfine structure; Rabi oscillation; Physics; Fysik;

   Sammanfattning : This thesis is based on a selection of six different experimental techniques used for studies in atomic and molecular physics. The techniques analysed in the thesis are compared to find similarities in strategies and ways to avoid sources of error.Paper 1 deals with collision based spectroscopy with 60 keV Xe6+ ions on sodium and argon gas targets.
