Phys. Rev. A 69, 043201 (2004) [6 pages]Ionization of cluster atoms in a strong laser fieldReceived 11 April 2003; revised 2 October 2003; published 5 April 2004 Inner and outer multiple ionization of clusters by a superintense ultrashort laser pulse is studied. The barrier-suppression mechanism governs inner field ionization in this case, while impact ionization can be neglected. Outer ionization produces a static Coulomb field inside the ionized cluster. This field increases the charge multiplicity of the atomic ions produced inside the cluster approximately by a factor of 1.5. Various models are suggested for the charge distribution inside the cluster. © 2004 The American Physical Society URL:
