  6. 4. Single-photon multiple ionization processes studied by electron coincidence spectroscopy

    Author : Per Linusson; Mats Larsson; Raimund Feifel; Stephen Price; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photoionization; multiple ionization; autoionization; synchrotron radiation; electron coincidence spectroscopy; fysik; Physics;

    Abstract : This thesis is based on studies of multiple ionization of atoms and molecules induced by the absorption of a single photon. For the experimental investigations a time-of-flight magnetic bottle spectrometer has been used to detect the emitted electrons in coincidence. READ MORE

  7. 5. Multi-Electron Coincidence Studies of Atoms and Molecules

    Author : Egil Andersson; Raimund Feifel; Jan-Erik Rubensson; Kiyoshi Ueda; Uppsala universitet; []
