title: Helium Droplets Doped with Sulfur and C60.
abstract: Clusters of sulfur are grown by passing superfluid helium nanodroplets through a pickup cell filled with sulfur vapor. In some experiments the droplets are codoped with C60. The doped droplets are collided with energetic electrons and the abundance distributions of positively and negatively charged cluster ions are recorded. We report, specifically, distributions of Sm+, Sm-, and C60Sm-containing up to 41 sulfur atoms. We also observe complexes of sulfur cluster anions with helium; distributions are presented for HenSm-withn≤ 31 andm≤ 3. The similarity between anionic and cationic C60Sm±spectra is in striking contrast to the large differences between spectra of Sm+and Sm-.
