摘要
We investigate by classical molecular dynamics the pre-fragmentation dynamics of a C60 molecule, occurring above 4500 K. and calculate the curve of the caloric equation of state. We discuss the solid-to-liquid transition displayed by C60 just below the disintegration temperature. Moreover, we report on the existence of a phase characterized by hoppings among different isomeric structures. A metastable liquid-like state is observed and discussed as well.
