Query: Inversion of Strong Field Photoelectron Spectra for Molecular Orbital
  Imaging   Imaging structures at the molecular level is a fast developing
interdisciplinary research field that spans across the boundaries of physics
and chemistry. High spatial resolution images of molecules can be obtained with
photons or ultrafast electrons. In addition, images of valence molecular
orbitals can be extracted via tomographic techniques based on the coherent XUV
radiation emitted by a molecular gas exposed to an intense ultra-short infrared
laser pulse. In this paper, we demonstrate that similar information can be
obtained by inverting energy resolved photoelectron spectra using a simplified
analytical model.
