Coincidence study of core-ionized adamantane: site-sensitivity within a carbon cage?

We investigate the fragmentation dynamics of adamantane dications produced after core-ionization at the carbon edge followed by Auger decay. The combination of high-resolution electron spectroscopy, energy-resolved electron-ion multi-coincidence spectroscopy and different theoretical models allows us to give a complete characterization of the processes involved after ionization. We show that energy- and site-sensitivity is observed even for a highly-symmetric molecule that lacks any unique atomic site.

Automated summary

We investigated the fragmentation dynamics of adamantane dications generated through core-ionization at the carbon edge and subsequent Auger decay. By employing high-resolution electron spectroscopy, energy-resolved electron-ion multi-coincidence spectroscopy, and various theoretical models, we were able to fully characterize the processes involved after ionization. Our findings demonstrate the observation of energy- and site-sensitivity even in a highly-symmetric molecule lacking any unique atomic site.
