Our computational procedure relies on a numerical solution of the time-dependent Schrödinger equation on a square-iKeywords: Photon energies; Total integrated cross section (TICS); Two-electron continuum; Two-photon double ionization; Computational methods; Correlation methods; Ionization; Photons; Schrodinger equation; Helium200710.1103/PhysRevA.75.0334112015-12-08
