摘要：

We present a quantitative physical model of above-threshold dissociation of homonuclear molecular ions in intense midinfrared laser fields. This allows us to describe self-consistently all three processes that occur during dissociative ionization of H-2 and D-2 (ionization of the neutral molecule, dissociation of the molecular ion, and its secondary ionization) using a semiclassical approach. The kinetic energy spectrum of the dissociating fragments is obtained and analyzed.
