Abstract
The method of computer simulations is employed to investigate the two-elect ron ionization of a model one-dimensional xenonlike atom with a femtosecond laser pulse. Based on the comparison of the results of exact simulations a nd calculations performed in the approximation of a "passive" electron, we analyze the contribution of the rescattering effect to the double ionizatio n of atoms. It is demonstrated that the formation of doubly charged ions is not reduced to the rescattering process.
