论文摘要
在掺杂的氦纳米光的电子电离后，形成了磷的正电荷簇离子。将红磷和磷酸盐样品的蒸气捡起中性和带电的氦纳米圆形。独立于所使用的条件，簇大小分布表现出明显的奇数振荡，这与文献中发表的几乎所有实验和理论模式相反。超流体的低温环境矩阵淬灭碎片，带电的磷簇类似于中性前体的结构。
Positively charged cluster ions of phosphorus were formed upon electron ionization of doped helium nanodroplets. The vapors of red phosphorus and a phosphate sample were picked up into neutral and charged helium nanodroplets. Independent on the conditions used, the cluster size distributions exhibit pronounced odd-even oscillations that are opposite to almost all experimental and theoretical patterns published in the literature. The low temperature environment of the superfluid He matrix quenches fragmentation and the charged phosphorus clusters resemble the structure of the neutral precursors.
