    Abstract

    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 enables one to extract the Wigner time delay directly from attosecond time delay measurements.
