Abstract
We compute above-threshold ionization electron spectra by solving numerically the time-dependent Schrödinger equation of a one-dimensional model atom in an external field, and compare the results with three Keldysh-type models worked out for the same atom. The Keldysh models offer an unreliable representation of the ionization process.Keywords
