Abstract

We consider the final stage of multiple ionization of atoms in a strong linearly polarized laser field within a classical model. We propose that non-sequential multiple ionization is dominated by symmetric escape from a highly excited intermediate complex. For a configuration of N electrons with C_Nv symmetry in a plane perpendicular to the electric field we analyze the classical motion in phase space and discuss the final momentum distribution parallel and perpendicular to the polarization axis. The results are in good agreement with recent experiment of multiple ionization in Ne.
