We consider the final stage of double ionization Of 02 molecules by
short linearly polarized laser pulses. The saddles of the effective
adiabatic potential energy close to which simultaneous escape of
electrons from a molecule takes place are identified. The analysis of
the saddles and numerical simulations of the ionization indicate that,
to observe clear signatures of simultaneous electron escape in double
ionization of O-2 molecules, stronger and much shorter laser pulses than
those used in the recent experiment.
