Photoionization cross sections for both atomic helium and molecular hydrogen have recently been calculated using a time-dependent close-coupling method. The total electronic wavefunction for the two electron system is expanded in six dimensions, where four dimensions are represented on a radial and angular lattice and a coupled channels expansion is used to represent the other two dimensions. The double photoionization cross sections obtained for both He and H2 for a range of photon energies above the complete fragmentation threshold were compared with absolute experimental measurements. Very good agreement is found with experiment. Our method is also capable of being extended to calculations of single and triple differential cross sections of H2.
