Synchrotron radiation in the tender x-ray energy range (2-13 keV) allows deep core-shell excitation/ionization of atoms and molecules. The electronic states populated have ultrashort lifetimes, in the order of one femtosecond. The atoms will then relax through emission of a photon or an electron. In this thesis, we used electron spectroscopy as a tool to study the different processes implied by the interaction between the matter and highly energetic radiation. In the first part, the lifetime of the excited electronic states is used as an intern clock allowing to measure nuclear dynamics in the sub-femtosecond timescale. The lifetime broadenings of the populated electronic states are large enough so that these states overlap, thus allowing t...
