Phosphorus cluster cations formed in doped helium nanodroplets are different

Positively charged cluster ions of phosphorus were formed upon electron ionization doped helium nanodroplets. The vapors red and a phosphate sample picked up into neutral Independent on the conditions used, size distributions exhibit pronounced odd-even oscillations that are opposite to almost all experimental theoretical patterns published in literature. low temperature environment superfluid He matrix quenches fragmentation clusters resemble structure precursors.
