Based on the mass spectrometric signals of neutral Cu-trimers obtained with a Secondary Neutral Microprobe we discuss if and how small sputtered metallic clusters are generated by agglomeration of individually ejected atoms from one single collision cascade. The agglomeration mechanism is discussed in detail as well as the formation of excited cluster states.

溅射生成的金属纳米团簇的形成：中性铜三聚体的模型研究

基于使用次级中性微探针获得的中性Cu-三聚体的质谱信号，我们讨论了是否以及如何通过单个碰撞级联中单个喷射的原子的团聚产生小的溅射金属簇。详细讨论了团聚机理以及激发团簇态的形成。
