The expressions for tunnel ionization probability of the complex atoms and atomic ions from arbitrary states in electromagnetic field are obtained. These expressions correctly describe the… Expand

The analytic expressions for the probabilities of tunnel ionization of atoms and atomic ions and for the energy and angular electron spectra in a strong low-frequency electromagnetic field are… Expand

Multiphoton ionization of atoms in intense laser-light fields is gaining ground as a spectroscopic diagnostic tool. In this volume, Delone and Krainov present both their own and other theoretical… Expand

The ionization of atoms in a low-frequency linearly polarized electromagnetic field (the photon energy is much lower than the ionization potential of an atom) is considered under new conditions, in… Expand

Experimental and theoretical data on tunneling and barrier-suppression ionization of atoms and atomic ions in a low-frequency laser radiation field are considered. The yields of single- and… Expand

Simultaneous measurements of neutrons result in zero yield, which proves the observation of neutronless fusion reactions in the authors' experiments.Expand
