摘要: The angular distribution of continuum electrons following double photoionization helium is calculated using a final-state wavefunction which accounts for Coulomb interactions between all three particles (nucleus and two electrons). Particularly in the case almost equal energies electrons, strong effects from electron repulsion on are predicted. Selection rules excluding certain momentum configurations proposed. When only one detected, agreement obtained with measured values asymmetry parameter beta its distribution.
