|Title:||Transport properties and interaction potential for Na+ ions in Xe gas||Authors:||Tan, T.L.
|Issue Date:||1994||Citation:||Tan, T.L.,Ong, P.P.,Hogan, M.J. (1994). Transport properties and interaction potential for Na+ ions in Xe gas. The Journal of Chemical Physics 100 (1) : 586-590. ScholarBank@NUS Repository.||Abstract:||The ratio, DT/K, of the transverse diffusion coefficient to mobility for Na+ ions drifting in Xe gas has been experimentally measured. Inevitable longitudinal end effects present in the drift tube were duly corrected for. Results at ∼303 K are reported at electric field to neutral gas density ratios, E/N, ranging from 5 to 440 Td. Furthermore, elaborate calculations of the reduced mobility, K0, the ratio, D L/K, of the longitudinal diffusion coefficient to mobility, and DT/K were calculated with a Monte Carlo simulation (MCS) method which used the interaction potential of Koutselos, Mason, and Viehland [J. Chem. Phys. 93, 7125 (1990)] as input. The accuracy of this potential has been evaluated by comparing the results with the experimental data and those calculated using the generalized Einstein relations technique. Agreement within 3% between the experimental values of DT/K and those from MCS calculations for the whole range of E/N suggests that the interaction potential represents fairly well the true potential. The error of the experimental measurements of DT/K is estimated to be better than 3.5% and that of the MCS calculations is better than 1% for K0 and 2.5% for D T,L/K. © 1994 American Institute of Physics.||Source Title:||The Journal of Chemical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/98446||ISSN:||00219606|
