Measuring the mobilities of the ions formed in P-10 mixtures

We measured the reduced mobilities (k₀ in cm²V^-1s^-1) of the ions that are formed in P-10 mixtures under different pressures and various reduced electric fields. Two types of ions were identified. We then used the extrapolated values of k₀ when E/N¿0 (2.41 and 2.76 cm²V^-1s^-1), the Langevin formula and the Blanc´s law, to calculate the masses of these ions. Calculations indicate that the two ions have masses of 41 a.u. and 25 a.u., respectively. We propose hypothesis to explain the nature and origin of those ions.
