摘要：

Analytic expression for the nonsequential transition rate in a linearly polarized laser field has been found, based on the adiabatic Landau-Dykhne approach. The formula involves electron-electron correlation through the mechanism of collective tunneling. The formula fails for a "knee" structure, but improves agreement with experimental results in the range of higher laser field intensities. A brief discussion on the dependence of the nonsequential transition rate on the laser pulse shape and wavelength was made.
