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– with n ≤ 31 and m ≤
3. The similarity between anionic and cationic C60Sm± spectra is in striking
contrast to the large differences between spectra of Sm+ and Sm–.
