Strong-field triple ionization of atoms with the p<sup>3</sup> and ns<sup>2</sup>p<sup>1</sup> valence shells studied with a reduced geometry model

ORAL

Abstract

Our basic understanding of multiphoton processes in atoms exposed to strong laser field is based on the single active electron picture. Effects like a multiple non-sequential ionization are beyond description in this approach. In such cases, classical or semi-classical descriptions are used typically [1, 2]. Yet, it is possible to construct a model with a reduced geometry that enables a quantomechanical study of triple ionization [3]. In such a case, a special attention must be paid to the electronic configuration of the target atom. We have studied the influence of the symmetry of initial wave function onto ionization yields in a 3-electron systems exposing the difference in hierarchy of processes contributing to triple ionization when comparing atoms with the p3 and ns2np1 valence shells [3,4]. Additionally, the effect of the third electron onto double ionization in those systems is investigated [5, 6].
