Electron Attachment and Electron Ionization of Helium Droplets Containing Clusters of C60 and Formic Acid
Masoomeh Mahmoodi-Darian, Elias Jabbour Al Maalouf, Samuel Zöttl +2
High-resolution mass spectra of helium droplets doped with C and formic acid (FA) are ionized by electrons. Positive ion mass spectra reveal cluster ions [(C)FA$_…
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…
Solvation of Silver Ions in Noble Gases He, Ne, Ar, Kr, and Xe
Masoomeh Mahmoodi-Darian, Paul Martini, Lukas Tiefenthaler +3
We use a novel technique to solvate silver cations in small clusters of noble gases. The technique involves formation of large, superfluid helium nanodroplets that are subsequently…
Atomic Gold Ions Clustered with Noble Gases: Helium, Neon, Argon, Krypton, and Xenon
Paul Martini, Lorenz Kranabetter, Marcelo Goulart +4
High-resolution mass spectra of helium droplets doped with gold and ionized by electrons reveal HeAu cluster ions. Additional doping with heavy noble gases results in NenAu…
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…
