Abstract
We show how the multiphoton-ionization matrix element for an atom in a laser field at intensities beyond the regime of perturbation theory can be calculated from the standard Floquet expansion of the electron wave function. We expand the harmonic components in a discrete complex Sturmian basis set, and we evaluate the resulting (divergent) sum for the matrix element by using the Pad\'e method. We present results for partial rates and angular distributions for hydrogen.
