Experimental ion mobility measurements in Ne-CF₄

In this paper we present the results of the ion mobility measurements made in gaseous mixtures of neon with carbon tetrafluoride (Ne-CF$_4$) at a total pressure 8 Torr (10.6 mbar) and for low reduced electric fields in the 10 to 25 Td range (2.4–6.1 kV$\\cdot$ cm$^{−1}\\cdot$bar$^{−1}$), at room temperature. The time-of-arrival spectra revealed only one peak, which was attributed to CF$_3^+$. The reduced mobilities obtained from the peak centroid of the time-of-arrival spectra are presented for Ne concentrations in the 5%–95% range.
