Based on the fact that the kinetic energy of one atom in small cluster still obeys the Boltzmann distribution, a statistical model is developed to predict the time consumed by a small cluster transforming from one isomer to another and is tested by vast molecular dynamics simulations of C12 isomers transformation in helium gas at high temperatures (2000–3500 K). Extrapolating the model to lower temperatures, we found that the time for the most probable isomer of C12 formed at 2500 K turning into the most stable one is more than 1012 years at room temperature.
