Competition of photon and electron emission in interatomic decay of heterogeneous noble gas clusters — •Lutz Marder¹, André Knie¹, Christian Ozga¹, Christina Zindel¹, Clemens Richter², Uwe Hergenhahn^2,3, Arno Ehresmann¹, and Andreas Hans¹ — ¹Institute of Physics, University of Kassel, Kassel, Germany — ²Leibniz Institute of Surface Modification, Leipzig, Germany — ³Max Planck Institute for Plasma Physics, Greifswald, Germany

Noble gas clusters represent prototype systems for the investigation of fundamental atomic and molecular processes. Van-der-Waals bonds enable new relaxation pathways not available in isolated systems. In recent years many of these have been studied, often using coincidence measurement techniques.

Here, we present our state-of-the-art experiment where both electrons and photons were detected in coincidence, which allows for investigation of multi-particle decay pathways after excitation with synchrotron radiation. The results show that the addition of krypton to pure neon clusters strongly alters the emission by the opening of a faster ionizing decay channel compared to the radiative decay.
