Phys. Rev. Lett. 85, 2280–2283 (2000)Suppressed Molecular Ionization for a Class of Diatomics in Intense Femtosecond Laser FieldsSee Also: Erratum Received 29 February 2000; published in the issue dated 11 September 2000 It is shown that the puzzling experimental observation of suppressed molecular ionization, in intense laser fields, of O2, and its absence in N2, is a symmetry induced dynamical effect. More generally, it is predicted that the ionization signal of the class of homonuclear diatomic molecules having valence orbitals with an antibonding symmetry (e.g., σu, πg) would be suppressed, but not those with a bonding symmetry (e.g., σg, πu). The suppression effect can be visualized as due to an effective destructive interference between the two subwaves of the ionizing electron emerging from the two atomic centers. © 2000 The American Physical Society URL:
