The (multiple) photoionization and subsequent fragmentation of the C 60 molecule was studied with the synchrotron radiation after removing electrons from the inner K-shell. Our intention was especially focused on the dynamics of the subsequent fragmentation. In addition to 'normal' (non-coincident) electron and ion time-of-flight spectroscopy, we investigated this topic with the help of an electron-electron-coincidence measurement. Our experiment shows that in these processes C q+ 60 ions with charge states up to 3+ and several smaller C q+ 60-2m fragments are formed. In addition, the broad peak besides the C(1s) line, usually referred to as the 'plasmon' peak, has been observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
