The advent of isolated attosecond XUV pulse sources marks a new era in attosecond science, pivotal for the investigation of core electron dynamics. Here the authors discover that the coherent Raman coupling between the cation states leads to extra timedelay between different transition channels by applying the attosecond transient absorption spectroscopy on the investigation of complex dynamics of strong field ionization of Krypton.
