“…MeV ion collisions predominantly lead to emission of valence electrons, and only collisions with very small impact parameters lead to inner shell ionization, as recently shown for 42 MeV C 6+ collisions with the gas-phase adenine nucleobase, where only about 4% of the total ionization cross section where due to K shell ionization. [39][40][41][42] A mass spectrum obtained aer 11.76 MeV C 4+ collisions with (dTGGGGT-2H) 2À is shown in Fig. 3a.…”
We have studied soft X-ray photoabsorption in the doubly deprotonated gas-phase oligonucleotide [dTGGGGT-2H]^2-. The dominating decay mechanism of the X-ray induced inner shell vacancy was found to be Auger decay...

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.
