Abstract	In this paper we present the results of the ion mobility measurements made in gaseous mixtures of xenon with carbon tetrafluoride (Xe-CF$_{4}$) for pressures ranging from 6 to 10 Torr (8-10.6 mbar) and for low reduced electric fields in the 10 to 25 Td range (2.4-6.1 kV⋅cm$^{−1}$⋅bar$^{−1}$), at room temperature. The time-of-arrival spectra revealed one or two peaks depending on the gas relative abundances, which were attributed to CF$_{3}^{+}$ and to Xe$_{2}^{+}$ ions. However, for Xe concentrations above 60%, only one peak remains (Xe$_{2}^{+}$). The reduced mobilities obtained from the peak centroid of the time-of-arrival spectra are presented for Xe concentrations in the 5%-95% range.
