Research output: Contribution to journalArticle


In a recent paper Becker et al., explain the greatest extinctions in the earth history at the P/Tr boundary by the impact of an extraterrestrial object and consider that hypothesis proven by the presence of C60 and C 60 endohedrally filled by helium and argon in extraterrestrial isotope ratio. This paper rises some analytical aspects of those determinations which do not seem to be sufficiently well founded.
