Synopsis

Atoms in strong radiation fields are interesting objects for study, and the research field that concerns itself with this study is a comparatively young one. For a long period after the scovery of the photoelectric effect. it was not possible to generate electro- magnetic fields that did more than perturb the atom only slightly, and (first-or er) perturbation theory could perfectly explain what was going on at those low intensities. The development of the pulsed laser bas changed this state of affairs in a rather dramatic way, and fields can be applied that really have a large, or even dominant influence on atomic structure. In the latter case, w speak of super-intense fields. Since the interaction between atoms and electromagnetic waves is characterized by many parameters other than the light intensity, such as frequency, iQnization potential, orbit time, etc., it is actually quite difficult to define what is exactly meant by the term 'super-intense'. Obviously the term does not have an absolute meaning, and intensity should always be viewed in relation to other properties of the system. An atom in a radiation field can thus best be described in terms of various ratios of the quantities involved. The nature of the system sometimes drastically changes if the value of one of these parameters exceeds a certain critical value, and the new regime could be called super-intense with respect to that parameter.

A propos du livre

Présentation de l'éditeur

Atoms in a strong radiation field are interesting objects. While, for a long time, first-order perturbation theory was adequate to explain low-intensity effects, the development of the pulsed laser has changed matters dramatically, allowing fields to be applied that have a large, or even dominant influence on atomic structure: super-intense fields. The term is actually quite difficult to define, however, and it has no absolute meaning. An atom in a radiation field can best be described in terms of the ratios of the quantities involved. In almost all cases, however, quiver motion is the dominant feature of all atomic physics in the super-intense regime. But this can result in a wide variety of phenomena, such as ionization, emission of radiation, exchange of excess photons with the field, double ionization, etc. All of these aspects are discussed in the present book, grouped under four main headings: Multiphoton ionization; Multielectron atoms; Hard radiation quanta; and Coherence and interference.
