Theoretical study of strong field nonsequential double ionization of atoms
POSTER
Abstract
We study the strong field nonsequential double ionization of atoms based on the recently developed quantitative rescattering theory and the traditional laser-free (e, 2e) theory. Both the correlated electron momentum spectra and the integrated longitudinal distribution of ions are evaluated. We found that Coulomb interaction between the two outgoing electrons plays a crucial rule in the correlated electron momentum spectra while the longitudinal momentum distribution of ions is insensitive to how the two outgoing electrons are treated. In addition, the CEP (carrier envelope phase) dependence of the ion momentum distribution is also investigated.
