THE FORMATION OF FULLERENES: CLUES FROM NEW C 60 , C 70 , AND (POSSIBLE) PLANAR C 24 DETECTIONS IN MAGELLANIC CLOUD PLANETARY NEBULAE

“…In combustion, one can get a high ratio (0.26-8.8), while in carbon vapor condensation the ratio is usually low (0.02-0.18) (e.g., Mansurov 2011). In addition, vapor carbon condensation experiments under H-poor conditions indicate that C 60 fullerenes are more than 50% of total large carbon clusters (Kroto et al 1985).…”

The formation of fullerenes: clues from new C60, C70, and (possible) planar C24 detections in Magellanic Cloud Planetary Nebulae

“…Laboratory studies show that the C 70 /C 60 ratio can tell us whether the formation of fullerenes is "bottom-up" or "top-down", meaning growth from smaller to larger, or decay from larger to smaller units, respectively (e.g., Mansurov 2011). In combustion, one can get a high ratio (0.26−8.8), while in carbon vapor condensation the ratio is usually low (0.02−0.18) (e.g., Mansurov 2011). In addition, vapor carbon condensation experiments under H-poor conditions indicate that C 60 fullerenes are more than 50% of total large carbon clusters (Kroto et al 1985).…”
