Abstract

We simulate the so-called “Rainbow Reconstruction of Attosecond Beating By Interference of Two-photon Transitions” (Rainbow RABBITT) technique with R-Matrix with Time-dependence (RMT) theory for neutral argon. We compute the energy-resolved spectral phase induced by the autoionizing [Ne]3s3p64p 1P resonance with simulations incorporating semi-relativistic atomic descriptions. This allows us to isolate the j = 1/2 and j = 3/2 spin-orbit component contributions to the energy-resolved spectral phase, and compare these against experiment. We analyse changes to the spectral phase resolved in energy and emission angle induced by the autoionizing state.
