C60 inflation: production of C62, C64, …

open access: yesInternational Journal of Mass Spectrometry and Ion Processes, 1994
Abstract The fullerenes, C 60 and C 70 , incorporate multiple C 2 groups into the cage when the solid is bombarded by a kiloelectron volt polyatomic ion beam. In the case of C 60 , C 62 to at least C 74 are produced but there is no enhanced formation of C 70 . The C 2 groups are derived from fullerene fragmentation and addition apparently occurs

Thermal Stability of Carbinofullerenes C38, C62, and C64

Physics of the Solid State, 2020
The thermal stability of recently predicted carbinofullerenes C38, C62, and C64 was examined using the molecular dynamics method. Their decomposition channels and temperature dependences of the lifetime were characterized. The activation energies and frequency factors in the Arrhenius law were determined.

Combinatorial diversity of C62 to C150 fullerenes

Vestnik of geosciences, 2022
We shortly report on the combinatorial variety of C62 to C150 fullerenes, obtained and characterized by symmetry point groups using original computer algorithms. It is established that all 28 symmetry point groups allowed for fullerenes are already realized in the range C20 to C140. The criteria of internal verification of the results are proposed.
