摘要：

We have studied the process of direct (nonsequential) two-photon double ionization of molecular hydrogen (H-2). Solving the time-dependent Schrodinger equation by an ab initio method, total (generalized) and single-differential cross sections are obtained at photon energies from 26 to 33 eV. Both parallel and perpendicular orientation of the molecule with respect to the laser polarization direction are considered, and the results are compared with previously calculated cross sections at 30 eV, as well as the predictions of a simple model.
