Extraction of the attosecond time delay in atomic photoionization using the soft-photon approximation

Ivanov, Igor; Kheifets, Anatoli


We use the soft-photon approximation to extract the Wigner time delay from atomic two-color photoionization experiments. Unlike the strong-field approximation, the present method does not require introduction of the Coulomb-laser coupling corrections and
