Abstract
Fragmentations of C60 in the laser ablation of C60 film has been analyzed by a space/time resolved optical spectrometry with the resolution of micron in space and ns in time. Observation of light emission with increasing spectral broadening in the period over 1 micro-second suggests that C60 decomposes in a series of fragmentation processes by ejecting C2 molecules in each step. The ejecting processes are found more violent towards later fragmentation events. The result is well explained in our model of laser ablation.
