Abstract 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.

掺杂氦纳米液滴中形成的磷簇阳离子是不同的

摘要 掺杂的氦纳米液滴通过电子电离形成带正电荷的磷团簇离子。红磷和磷酸盐样品的蒸汽被吸收到中性和带电的氦纳米液滴中。独立于所使用的条件，簇大小分布表现出明显的奇偶振荡，这与文献中发表的几乎所有实验和理论模式相反。超流体 He 基质的低温环境淬灭了碎片，带电的磷簇类似于中性前驱体的结构。
