We investigate the dynamics of a one-dimensional [Formula Presented] model molecule in strong laser fields by numerical integration of the time-dependent Schrödinger 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 [Formula Presented] 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.
