On the thermal stability of some quasi-fullerenes

The thermal stability of recently predicted quasi-fullerenes С$_{20}$, С$_{42}$, С$_{48}$, and С$_{60}$ is studied by the method of molecular dynamics. The routes of their decomposition and the temperature dependences of their lifetimes are determined. The activation energy and frequency factor values that appear in the Arrhenius law are found. New isomers are detected.
