@article{Mcguire1981TwoAT, title={Two- and three-photon ionization in the noble gases}, author={E. J. Mcguire}, journal={Physical Review A}, year={1981}, volume={24}, pages={835-848} }

By using a characteristic Green's function for an exactly solvable Schroedinger equation with an approximation to the central potential of Hermann and Skillman, the cross section for nonresonant two- and three-photon ionization of Ne, Ar, Kr, and Xe were calculated in jl coupling. Expressions for cross sections in jl coupling are given. Comparison with the Ar two-photon cross section of Pindzola and Kelly, calculated using the many-body theory, the dipole-length approximation, and LS coupling… Expand
