This paper reviews the knowledge of the structure, dynamics and collisions of atomic
negative ions, as accumulated at the end of 2003, and describes how the research exploring …

The quasistationary quasienergy state approach (QQES) is applied to the analysis of partial
(n-photon) decay rates and angular distributions (ADs) of photoelectrons produced by an …

Publisher Summary This chapter illustrates that the development of lasers capable of
delivering short pulses of very intense radiation, over a wide frequency range, has led to the …

The solution of the many-electron many-photon (MEMP) problem for strong fields is
facilitated if the corresponding theory entails a computational methodology that combines …

We present a two-active-electron (TAE) approach for solving the time-dependent
Schrödinger equation (TDSE) for the interaction of a multi-electron system with an ultrashort …

R-matrixcalculations of the electron collisions with a lithium atom at energies below the 3 s
excitation threshold are presented. The S e 1, S e 3, and P o 1 phase shifts calculated in the …

We perform Floquet calculations of multiphoton ionization of argon in a KrF laser field for
intensities up to 10 14 W cm-2. As far as we are aware these results are the first ab initio …

Using the R-matrix Floquet approach, we investigate two-photon emission of a 2p electron
from the 1s 2 2s 2 2p 5 ground-state of Ne+ irradiated by laser light with photon energies …

We have nonperturbatively computed dc-field tunneling rates, linear and nonlinear dynamic
polarizabilities, and two-, three-, four-, and five-photon ionization rates for He, for …

Single and multiphoton detachment rates have been calculated for Na-using the R-matrix
Floquet approach. In the low-intensity limit the results are in agreement with other recent …
