Today the one?photon double ionization processis considered closed, inasmuch as full agreementhas been obtained between theory and experiments.On the other hand, the two-photoncase is far more difficult to deal with, especiallyexperimentally because of the weak twophotonionization yield. Non-sequential two?photon double ionization (TPDI) of helium isthe simplest system where such processes occur;discrepancies between several theoreticaldescriptions and with exper
