Abstract
It is shown that kilovolt collisions of C 60 + with helium result in not only the expected dissociation to yield smaller fragment carbon cluster ions but also the formation of fullerene-helium adduct ions corresponding to CxHe+, where x is even and varies from 48 to 58, in agreement with Schwarz et al. This report provides the first unambiguous identification of the C60He+ product, indicating that the helium adduct formation does not require fragmentation. Using hybrid tandem mass spectrometric techniques the mechanism of the formation of these unusual adduct species was investigated. The nature of the collisions, the energetics of the process, and the products of dissociation of C60He+, provide strong evidence that the helium atom is inside the fullerene cage structure.
