Book Description
Multiphoton lonization of Atoms provides a pedagogical review of the whole subfield of multiphoton ionization of atoms. This book discusses the "normal multiphoton ionization of atoms; calculation of resonant multiphoton processes; and angular distribution of photoelectrons and light polarization effects in multiphoton ionization of atoms. The multiphoton ionization involving continuum-continuum transitions; creation of doubly charged strontium ions; and many-electron processes in nonlinear ionization of atoms are also elaborated. Other topics include the non-resonant multiphoton ionization of atoms; above-threshold ionization theory; autoionizing states in multiphoton transitions; and specific features of the spectra of alkaline-earth atoms. This publication is beneficial to physics students and researchers conducting work on the multiple ionization of atoms.

Book Description
The objective of the research under this contract is to carry out studies of resonant enhanced multiphoton ionization (REMPI) processes in molecules. In the (n+1)-REMPI process of interest an atom or molecule in a specific initial state absorbs n photons making a transition to an intermediate state from which it is subsequently ionized by absorption of an additional photon. The studies are designed to provide a quantitatively robust analysis and prediction of key spectral features in several ongoing experimental studies and potentially practical applications of this technique. The specific problems of interest to the authors in these studied are (1) the vibrational distributions of ions that can be expected in REMPI of small molecules and molecular fragments with particular emphasis on their non-Franck-Condon behavior. Such non-Franck-Condon behavior introduces serious complications in the use of the technique for state-specific production of ions, e.g., O2([nu]) and OH([nu]), and in the extraction of state populations from REMPI signals, (2) rotational distributions of ions that can be produced in various REMPI schemes and how these distributions can be tuned by choice of the resonant state and influenced by the molecular character of the photoelectron, and (3) the circular dichroism in photoelectron angular distributions, i.e., the difference in photoelectron angular distributions produced by right- and left-circularly polarized, and their use as a probe of molecular alignment. Here the author will summarize the progress that has been made to date in the studies of these features and applications of REMPI of molecules and molecular fragments. A significant feature of these studies, which will be explicitly assumed throughout the discussion below, is that they are carried out using quantitatively reliable molecular photoelectron orbitals.

Book Description
Since the turn of the century, the increasing availability of photoelectron imaging experiments, along with the increasing sophistication of experimental techniques, and the availability of computational resources for analysis and numerics, has allowed for significant developments in such photoelectron metrology. Quantum Metrology with Photoelectrons, Volume 1: Foundations discusses the fundamental concepts along with recent and emerging applications. The core physics is that of photoionization, and Volume 1 addresses this topic. The foundational material is presented in part as a tutorial with extensive numerical examples and also in part as a collected reference to the relevant theoretical treatments from the literature for a range of cases. Topics are discussed with an eye to developing general quantum metrology schemes, in which full quantum state reconstruction of the photoelectron wavefunction is the goal. In many cases, code and/or additional resources are available online. Consequently, it is hoped that readers at all levels will find something of interest and that the material provides something rather different from existing textbooks.

Book Description
This book presents a detailed, modern description of the ionization of atoms by strong laser radiation. The authors present descriptions of processes occurring in atoms under the action of strong electromagnetic radiation, in particular, the shift, broadening, and mixing of atomic states. The topics include tunneling ionization, above-threshold ionization, ionization of multiply charged ions, resonance-enhanced ionization, super-intense radiation fields, and properties of Rydberg states strongly perturbed by laser radiation.
