Abstract

An improved quasistatic model is used to describe the ionization process of atoms in intense linearly polarized fields. Numerical calculations of above-threshold-ionization (ATI) energy spectra and photoelectron angular distributions (PAD) of hydrogen atoms clearly reveal a plateau and side lobe structures, which are in good agreement with recent ATI experiments. Our results show that the existence of this plateau and the side lobes is a consequence of the classical kinematics of the electrons in combined atom and laser fields. Furthermore, we find that the onset of these unusual phenomena is related to the onset of chaotic behavior in the system.
