Spectroscopy of Cs attached to helium nanodroplets
Journal of Chemical Physics
Cesium oligomers are formed on Helium nanodroplets which are doped with one or a few Cs atoms. The monomer absorption of the first electronic p ← s transition upon laser excitation is probed. Spectra employing laser-induced fluorescence, beam depletion and resonant photo-ionization are compared. In particular, mass-resolved photo-ionization allows us to specifically probe excitation induced processes such as e.g. the formation of cesium-helium exciplexes. Absorption spectra of Cs dimers anddoi:10.1063/1.1805508 pmid:15527352 fatcat:7copwxzdjjb67h7i2ahawbimju
