“…It turns out that the triple and critical point temperatures, T tr and T cr , are significantly lower, and much higher, respectively, of their counterparts for a rigid cage model of C 60 . 10,11,13,[15][16][17] We get thus evidence of a huge expansion of the stable liquid phase pocket of C 36 in comparison to that early found in C 60 . 10-12, 14, 16, 17 Moreover, the diffusion coefficient and the structural arrangement at the triple point density of C 36 , maintain liquid-like features over several hundreds degrees below T tr , by thus indicating a substantial extension of the "supercooled" liquid region.…”
