摘要：
The Landau-Dykhne approximation for the spectrum of above-threshold electrons produced upon ionization of atoms by a monochromatic laser field is used to calculate the spectrum in the case of ionization by a short laser pulse. The spectra obtained in this way are compared with those calculated by the adiabatic theory. The comparison shows that the Landau-Dykhne approximation with the properly chosen exponential factor describes well the averaged spectrum.
