    "abstract": "We outline a formalism and develop a computational procedure to treat the\nprocess of multiphoton ionization (MPI) of atomic targets in strong laser\nfields. We treat the MPI process nonperturbatively as a decay phenomenon by\nsolving a coupled set of the integral Lippmann-Schwinger equations. As basic\nbuilding blocks of the theory we use a complete set of field-free atomic\nstates, discrete and continuous. This approach should enable us to provide both\nthe total and differential cross-sections of MPI of atoms with one or two\nelectrons. As an illustration, we apply the proposed procedure to a simple\nmodel of MPI from a square well potential and to the hydrogen atom.",
