The most stable structures of carbon clusters were optimized by the parallel fast annealing evolutionary algorithmbased on the Brenner potential.

将并行快速退火演化算法结合Brenner 势能函数用于小碳原子簇C_n(n=2-20)的结构优化,得到了最稳定构型:C_2-C_4为线型结构;C_5-C_(17)为单环;C_(18)和C_(19)为类富勒烯的笼状结构;C_(20)为最小的富勒烯。

According to this approach,the relative abundence of clusters with similar structural configurations and stabilities can be fitted by a single lognormal curve and the number of distribution curves in a mass spectrum corresponds to the number of different configuration of clusters,so we can correlate the mass spectra of carbon clusters with their structures.
