Abstract

We present a method for obtaining the internuclear separation ofdiatomic molecular ion H2+ irradiated byattosecond-duration laser pulse, by computing the probability flux ofwavefunction pattern of photoelectron in configuration space. Incontrast to earlier means of attosecond-scale time-gating or takingratio of image data in momentum space, our alternative is characterizedby experimental feasibility. The numerical results of areduced-dimensionality model on hydrogenic ions corroborated our methodare obtained and can be generalized to more complex molecular systemsfor inferring bond length or bond angle information.
