Abstract
A quantum version of the Drude-Lorentz model of the atom is used to study abnormally large energy transfers found in recent ionization experiments by strong laser fields. It is argued that collective excitations greatly enhanced by parametric resonance may lead to an exponential growth of the atomic energy with time. It is shown that the repulsion between the electrons plays an essential role, reducing the frequency at which parametric resonance occurs.Keywords
