    "abstract": "We employ the Kramers-Henneberger Hamiltonian for time-independent\ncalculations of multi-photon ionization of atoms with one and two electrons. As\ncompared to the electromagnetic interaction in the length and velocity gauges,\nthe presently employed Kramers-Henneberger gauge has an advantage of the dipole\nmatrix elements for the free-free electron transitions being finite and\nwell-defined quantities. This circumstance simplifies considerably the\ncomputations and allows to obtain accurate results for the two-photon\nionization of realistic atomic systems.",
