The average numbers of scintillation photons and electrons produced by an α-particle with 5.49 MeV were determined in high-density xenon gas in the density range of 0.03-0.12g/cm3. No significant density dependence was observed for the number of excited atoms or liberated electrons. The average energies expended per excited atom (Wex-value) and liberated electron (W-value) were found to be 34:1 ± 2:4 and 20:9 ± 0:4eV, respectively. It was also found that some liberated electrons escape from recombination at zero electric field.
