【 摘 要 】

At the critical point of fragmentation phase transition occurring in C60system, we found that the yield distribution of ionic fragments Cn+(n=3-16) originating from the multi-fragmentation pattern can be approximated fairly well by a power-law attenuation form of n-λ. Under the framework of Fisher model, the experimental result implies that the ionization-degree distribution of fragments obeys a power law enhancement form as the size n.
