Large polyatomic molecules typically exhibit low ionization potentials, Ip,leading to over-the-barrier ionization (OBI) already at relatively lowintensities (~1013 W/cm2). We revisit laser-induced electron diffraction (LIED)in the over-the-barrier ionization (OBI) regime and answer the question ofwhether imaging of molecular structure is still possible with LIED. We employ ahydrogen-like model system mimicking a molecule with low Ip using a classicaltrajectory-based model (CT) that incorporates the Coulomb potential; we alsouse the numerical solution to the time-dependent Schrodinger equation (TDSE).Specifically, we adopt the Fourier transform variant of LIED (FT-LIED) to showthat even a significant contribution of short trajectories in the OBI regimedoes not preclude structure retrieval from strong-field diffractive patterns.This theoretical investigation shows that LIED can be well described by theclassical recollision model even when ionization occurs within the OBI regime.This study paves the way towards strong-field imaging of chemicaltransformations of large polyatomic molecules in real-time based onstrong-field electron recollision.
