A study was conducted on the dynamics of a model H2 molecule driven by strong laser fields without adopting the Born-Oppenheimer approximation. It was found that for constant intensity the decay of the molecule can be described by a single decay rate. The results indicate that single ionization at short internuclear distances was the main route of decay. Hence, double ionization of H2 at small internuclear distances was said to be responsible for high-energy protons based on the observations in the Coulomb-explosion experiments.
