dc.description.abstract | The ratio of the transverse diffusion coefficient to mobility, DT/K at 309 K for Li+ ion swarms drifting in Kr gas in the E/N (electric field to neutral gas number density ratio) range of 5 to 170 Td, was experimentally determined with an overall accuracy of ±4%. The DT/K results were effectively corrected for longitudinal end effects present appreciably in the drift tube by an analysis which requires the measurement of variance x2 of the transverse ion-current density profile at different drift lengths z and the derivation of the magnitude a2 of the end effects. Good agreement of the results with those calculated by Monte Carlo simulations (MCS) using an established interaction potential demonstrates the accuracy and reliability of the present DT/K results. In addition, elaborate calculations of the reduced mobility K0 and ratio DL/K of the longitudinal diffusion coefficient to mobility of the Li+-Kr system are calculated with the MCS method. The accuracy of the MCS calculations is estimated to be ±2.5%. The calculated DL/K values are compared with the experimental data available in the literature. Both DT/K and DL/K values for Li+ in Kr were also derived using reduced mobility K0 data obtained from the MCS calculations and from experimental data, employing the generalized Einstein relations based on the three-temperature theory. © 1995 The American Physical Society. | |
