Summary
-The rescattering mechanism for double ionization of D2 is clearly identified.
-It is quite competitive with CREI at low intensities, but grows less rapidly than CREI. It cannot be seen in singles spectra because of competing processes.
-The general characteristics:
Order of magnitude of probability
are consistent with a simple model of rescattering process.
-We need a solution to the two electron Schroedinger equation for this process.
