Title: | Monte Carlo calculations of drift velocities and diffusion coefficients of Ar+ ions in helium | Authors: | Barata, J. A. S. Conde, C. A. N. |
Keywords: | Ion mobility; Diffusion coefficients; Monte Carlo simulation; Ion transport in gases | Issue Date: | 2007 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 580:1 (2007) 18-21 | Abstract: | Results are presented for the calculated drift velocities and diffusion coefficients for Ar+ ions in helium at atmospheric pressure, temperature T=300 K and for reduced electric fields E/N from about 1 Td up to about 150 Td, using Monte Carlo techniques. The drift velocities range from 5.94×103 to 559.0×103 cm s-1 for the Ar+ ions in the ground state 2P3/2 and from 5.85×103 to 545.0×103 cm s-1 for the Ar+ ions in the metastable excited state 2P1/2. These values are in good agreement (within about 5%) with the few experimental values available. The mobilities and diffusion coefficients for atomic Ar+ ions in helium gas show no significant dependence on the spin state of the ion. | URI: | https://hdl.handle.net/10316/4353 | DOI: | 10.1016/j.radphyschem.2004.04.079 | Rights: | openAccess |
