Unexpected Polarization Transfer Echos in Atomic Inner-Shell Two-photon Ionization — •Jiri Hofbrucker1,2,3, Andrey Volotka1,3, and Stephan Fritzsche1,2,3 — 1Helmholtz-Institute, Jena, Germany — 2Friedrich-Schiller Universität, Jena, Germany — 3GSI, Darmstadt, Germany
Unexpected polarization transfer from incident to fluorescence photon is discovered in the case of two-photon inner-shell ionization by circularly polarized light. Beside the expected complete polarization transfer induced at incident photon energy tuned to intermediate resonances, echos of the polarization transfer occur at higher nonresonant incident photon energies due to vanishing of the dominant ionization channel. Measuring the polarization properties of the fluorescence light promises an opportunity to extract ionization properties out of an experiment with an unprecedented accuracy and carry out a critical comparison with available theory.
