    Sammanfattning : The new generation of high resolution astronomical instruments such as the Hubble Space Telescope (HST) or the Very Large Telescope (VLT) has renewed the demand for accurate atomic parameters like wavelengths, oscillator strengths and line profiles accompanied by reliable uncertainty estimates. Fourier transform spectroscopy has proven to be a powerful tool when measuring these parameters. LÄS MER

    Författare :Sergey Peredkov; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supraconductors; magnetic resonance; relaxation; spectroscopy; magnetic and optical properties; rare-gas clusters; Condensed matter:electronic structure; electrical; metal clusters; photoemission; synchrotron radiation; core-level spectroscopy; Auger decay; XPS; nano-particles; free clusters; egenskaper elektriska; spektroskopi; magnetisk resonans; magnetiska och optiska ; supraledare; Kondenserade materiens egenskaper:elektronstruktur;

    Sammanfattning : The main topic of this Thesis is the x-ray spectroscopic studies of free nano-clusters with size more than 10^3 atoms. The photoelectron spectroscopy experiments on rare gas and metal clusters were performed at beamline I411 at MAX-lab National Swedish synchrotron radiation facility. Free rare-gas clusters are simplest objects in cluster research. LÄS MER
