摘要
We investigate the dynamics of a one-dimensional H-2 model molecule in strong laser fields by numerical integration of the time-dependent Schrodinger equation without the use of the Born-Oppenheimer approximation. Ionization typically occurs at internuclear separations close to the ground-state equilibrium distance. This is contrary to the case of H-2(+), which ionizes at larger internuclear distances where charge-resonance-enhanced ionization is possible. Similar to the case of atoms, we find considerable nonsequential double ionization.
