    "abstract": "The motion of electrons and ions in medium-sized rare gas clusters (1000\natoms) exposed to intense laser pulses is studied microscopically by means of\nclassical molecular dynamics using a hierarchical tree code. Pulse parameters\nfor optimum ionization are found to be wavelength dependent. This resonant\nbehavior is traced back to a collective electron oscillation inside the charged\ncluster. It is shown that this dynamics can be well described by a driven and\ndamped harmonic oscillator allowing for a clear discrimination against other\nenergy absorption mechanisms.",
