Photo Double Ionization of fixed in space D2:
In a first experiment we have detected both D+ ions in coincidence with one of the two electrons. The kinetic energy release of the molecular fragment could be well described by an adapted reflection approximation. ![]() Energy and momentum of electrons and ions for double ionization of D2 27eV above threshold. Upper left: electron energy distribution, Lower right: Ion energy distribution, upper right: correlation between the energy of one electron and one ion. lower left: momentum distribution of D+ ions, the polarization is horizontal. ![]()
Angular distribution of one electron for double ionization of He and D2 at the same excess and electron energy.
left: Helium, middle and right D2 the direction of the molecular axis is indicated. |
