Double photoionization of atoms in the J-matrix approach
The application of the J-matrix version formulated for the description of the three-body Coulomb system to two-electron single-photon ionization processes is discussed. Triple-differential cross sections of (γ, 2е) reactions have been calculated. Results are rather close to the experiment.
Keywords: helium atom, beryllium atom, photoionization, three-body system, cross section, J-matrix method
