Phys. Rev. A 65, 033403 (2002) [8 pages]Strong-field ionization dynamics of a model H2 moleculeReceived 28 August 2001; published 1 February 2002 We investigate the dynamics of a one-dimensional H2 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 H2+, 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. © 2002 The American Physical Society URL:
