Multiphoton Double Ionization of H$_2$

Multiphoton double ionization probabilities for H$_2$ are calculated using a time-dependent close-coupling method. Total double ionization probabilities are calculated for 2, 3, and 4 photon absorption in the energy range from 10 eV to 50 eV. Single and triple differential probabilities are calculated at photon energies where the total ionization probability is near a maximum.
