We present a combined experimental and theoretical study of fragmentation of small Cn clusters (n = 5,7,9) produced in charge transfer collisions of fast (nu = 2.6 a.u.) singly charged Cn+ clusters with He. Branching ratios for all possible fragmentation channels have been measured. Comparison with microcanonical Metropolis Monte Carlo simulations based on quantum chemistry calculations allows us to determine the energy distribution of the excited clusters just after the collision.
我们展示了一项关于小Cn团簇（n = 5,7,9）碎片化的实验与理论相结合的研究，这些小Cn团簇是在快速（ν = 2.6 a.u.）单电荷Cn+团簇与He的电荷转移碰撞中产生的。已测量了所有可能碎片化通道的分支比。与基于量子化学计算的微正则Metropolis蒙特卡罗模拟进行比较，使我们能够确定碰撞后瞬间激发团簇的能量分布。
