Gaseous ion mobility of CO+ ions in He and Ne

Analysis of c harged particle transpo rt in dilute gases under the infl uence of electric fields has theoretical and practical applications in science and technology [۱-۳]. Investi gation of ions mobility in gases is an important issue in plasma che mistry, atmospheric physics, and numerical simul ations of in dustrial pla sma . There is now a la rge amount of data available for such analysis. H ere, we compare ion mobilities calculated from the (n,۶,۴) and the Pira ni's potentials with th e experimen tal values for the two systems He -CO+ and Ne-CO+. The parameters o f (n,۶,۴) po tential model and Pi rani's potential for He-CO+ and Ne-CO+ system s were obtained from experimental gaseous ion-mobility data. These potentials were then used to calculate the mobility of CO+ ions in helium and neon gases at ۳۰۰ K. Results show good agreem ent betwee n the ion mobility data calculated via the ( n,۶,۴) poten tial and experim ental data. The Pirani's potential yields ion mobilities of a lower accuracy especially for He-CO+.
