Core Relaxation Effects in Molecular Photoionization,alence (outer-shell) electrons in response to the reduced shielding of the nuclear attraction.. This adjustment of the valence electrons, referred to as electronic relaxation, leads to a significant energy lowering of the final ionic state relative to a state where the valence electron distribution

High Resolution Electron Spectrometry of Atoms,re and electron dynamics of free atoms. This technique, as an experimental tool, follows the dynamics of the electrons in the atom as they respond to an initial excitation, and the spectral resolution available depends on the conditions of the experiment. For example, in Auger electron spectrometry

Photoion-Pair Formation,the absence of collisional and field effects, and taking into account thermal Boltzmann effects, this process has a threshold which (if Franck-Condon effects are not too restrictive) is the adiabatic ionization potential. In Some cases, ionization can arise from a quite different process—the formati

Electronic and Nuclear Relaxation Of Core-Excited Molecules,upling to nuclear motion. For molecules built with light atoms, the Auger decay rate dominates largely the x-ray fluorescence rate and so we will concentrate on the effect of . through Auger-like processes. In contrast to atoms, molecules which are stripped of several outer valence electrons through

Resonances and Near-Threashold Processes,the incident photon excites the ionic state just above its threshold so that the outgoing electron has a very small, nominally zero energy, and this can have profound influence on the dynamics of the process. In particular, electron correlations can become dominant.

Resonant and Nonresonant Auger Recombination,he initial stage of the normal Auger process the atom is singly ionized. In the high-energy limit of the photoionization process the atom first relaxes in its core hole state. In a practically distinct second step, the core hole is then filled by an outer electron and the excess energy is released b

Laser-Based UV and VUV Spectroscopy of Doubly Excited Atoms,e highly excited states in the photoionization continuum of free atoms. The methods involved, which are comparatively new, are described, and the relative advantages and disadvantages of tunable laser versus synchrotron radiation sources are explained. Examples of recent spectra are then given, draw
