Mass and optical spectroscopic methods are used for the analysis of copper (Cu) atoms and clusters
doped to helium nanodroplets (He N ). A two-color resonant two-photon ionization scheme is applied to study the Cu 2 P◦ 1/2,3/2←2 S 1/2 ground state transition. The absorption is strongly broadened for Cu atoms
submerged inside helium nanodroplets and a comparison with computed literature values is provided.
An observed ejection of the dopant from the droplet is triggered upon excitation, populating energetically lower states. The formation of Cun clusters up to Cu 7 inside helium nanodroplets was observed by means of electron impact ionization mass spectroscopy.
