Abstract
The thermal stability of the (C20)2 cluster dimer consisting of two C20 fullerenes has been numerically examined using the tight-binding method. The simulation of the dynamics of the (C20)2 dimer at temperatures of T = 2000–3500 K shows that the finite lifetime τ of this metastable system is determined by two fundamentally different processes: the decay of one of the C20 fullerenes and the coalescence of two C20 fullerenes to the C40 cluster. The activation energies for these processes. E a ≈ 3.4 and 2.7 eV, respectively, as well as their frequency factors, have been determined by analyzing the τ(T) dependence.
