Relativistic photoionization delays and the role of auto-ionizing resonances

We measured the relative ionization delays into the two spin-orbit components of the electronic ground states of Xe+ and Kr+ under the inuence of auto-ionizing intermediate and final states. The results are in good agreement with state-of-the-art calculations based on the time-dependent configuration-interaction singles (TDCIS) approach.ISSN:1742-6588ISSN:1742-659
