Multiple ionization of argon atoms by long-wavelength laser radiation: a fermion molecular dynamics simulation

We applied the method known as fermion molecular dynamics to the description of an isolated argon atom interacting with a short pulse of intense, long-wavelength laser radiation, for both linear and circular polarization. We discuss the results of these calculations, insofar as they bear on the mechanisms leading to the production of high-ionic-charge states during laser-atom interaction.
