Many-photon ionization, resonance scattering on a nonstationary potential, and complex poles of the $S$ matrix

V. N. Ostrovskii


Abstract: The problems of multiphoton ionization and resonance scattering on nonstationary potential are considered from the viewpoint of the location of the poles of the scattering matrix on the complex quasienergy plane. Variational principle is formulated which makes it possible to determine at the same time the position and the width of the quasienergy level. Trajectories of the poles with changing of the parameters of the problem are investigated.
