Abstract: | Electronic excitations of Xe atoms and Xe2 molecules embedded in free Ne clusters are studied with time resolved fluorescence excitation spectroscopy. Several distinct absorption bands blueshifted relativ to the first atomic resonance line of Xe are observed and are attributed to Xe or Xe2 located in different sites. For Ne clusters containing less than 300 atoms only interior sites are observed indicating that small Ne clusters are liquid-like. |
