Effect of deuteration on methane cluster stability
Ake Andersson, Klavs Hansen, Siegfried Kollotzek +2
The evaporation from clusters of mixed deuterated and protonated methane molecules has been studied experimentally and theoretically. Only loss of the two components CH and CD$…
Hydrogen isotope mixing entropy in ammonia clusters
Klavs Hansen, Åke Andersson, Johannes Reichegger +2
Measured evaporation branching ratios of partially deuterated isotopologues of protonated ammonia clusters (NH) H () show ratios that depend only on the clust…
Isotope enrichment in neon clusters grown in helium nanodroplets
Lukas Tiefenthaler, Siegfried Kollotzek, Michael Gatchell +3
Neon cluster ions Ne grown in pre-ionized, mass-to-charge selected helium nanodroplets (HNDs) reveal a strong enrichment of the heavy isotope Ne that depends on cluste…
Proton transfer at subkelvin temperatures
Lukas Tiefenthaler, Siegfried Kollotzek, Andrew M. Ellis +2
We demonstrate a novel method to ionize molecules or molecular clusters by proton transfer at temperatures below 1 K. The method yields nascent ions and largely eliminates secondar…
Phosphorus cluster cations formed in doped helium nanodroplets are different
Simon Albertini, Faro Hechenberger, Siegfried Kollotzek +8
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…
