TL;DR: In this paper, the effects of initial-state correlation were studied by comparing cross sections obtained using a configuration-interaction-type initial state wave function with those obtained by a Hartree-Fock initial-State wave function, and they found that earlier single-center cross sections were not well converged with respect to their expansion parameters.

TL;DR: In this paper, a quantitative rescattering theory for high-order harmonic generation (HHG) by intense laser pulses is presented, which can be expressed as a product of a returning electron wave packet and the photorecombination differential cross section of the laser free continuum electron back to the initial bound state.

TL;DR: In this article, a quantitative rescattering (QRS) theory was proposed to explain the strong field phenomena of high-order harmonic generation, high-energy above-threshold ionization and non-sequential double ionization.

TL;DR: In this article, a detailed overview of variational functions and their applications in photoionization and electron-molecule collisions is presented, as well as a detailed discussion of the numerical and computational procedures used in applications.

TL;DR: In this article, a new computational approach has been used to evaluate the rotationally summed, vibronically elastic integral cross sections from the scattering of slow electrons (energy ranging from 1.0 eV up to 40 eV) by tetrafluoromethane molecules in the gas phase.
