Beschreibung
Electron spectroscopy has long been a cornerstone for studying the dynamics of ion-atom/molecule collisions [1], offering detailed insight into fundamental processes such as electron capture, ionization, and excitation [2-4]. Extending electron spectroscopy to ion-ion collisions — where both collision partners are charged — is an emerging and largely unexplored frontier. Such studies enable the determination of ionization cross sections in pure three-body systems, allowing for a systematic investigation of the role of additional electrons by controllably varying the electrons carried from the colliding ions, and providing a testing ground for theories. In this context, we present the concept of developing a novel electron spectrometer designed to inaugurate Ion-ion COllisioN Electron Spectroscopy (ICONES). This setup will be implemented within the FISIC platform, which aims to explore ion-ion collisions in the hitherto unexplored intermediate energy regime [5]. The ICONES project is supported by the European Union under a Marie Skłodowska-Curie Postdoctoral Fellowship and provides an upgrade to the FISIC setup, which is currently being commissioned at the Institute of NanoSciences of Paris (INSP), Sorbonne University.
