摘要：

The two-photon ionization rate for the lithium atom is calculated in the time-dependent Hartree-Fock approximation for a variety of intensities and photon frequencies. The time-dependent equation for the valence Hartree-Fock orbital is solved on a two-dimensional cylindrical-coordinate lattice using both fixed and variable grid spacings. The nonperturbative results are compared with previous perturbation-theory results at photon energies near the 2s --> 3p single-photon resonance.
