The average numbers of scintillation photons and electrons produced by an $\alpha$-particle with 5.49 MeV were determined in high-density xenon gas in the density range of 0.03–0.12 g/cm3. No significant density dependence was observed for the number of excited atoms or liberated electrons. The average energies expended per excited atom ($W_{\text{ex}}$-value) and liberated electron ($W$-value) were found to be $34.1\pm 2.4$ and $20.9\pm 0.4$ eV, respectively. It was also found that some liberated electrons escape from recombination at zero electric field.
