TY - JOUR ID - 197272 AU - Trunec, David PY - 1995 TI - Determination of cross section for Ar+ - He elastic collisions from drift velocity data: Monte Carlo simulation JF - International Journal of Mass Spectrometry and Ion Processes VL - 149/150 IS - 1 SP - 179 EP - 179 PB - ELSEVIER SCIENCE BV SN - 01681176 N2 - The Monte Carlo simulation of the motion of Ar+ ions in He buffer gas in a uniform electric field has been carried out. The total cross-section for elastic collisions between the Ar+ ion and the He atom was considered in the form sigma(T)(v) = C/v where v is the relative velocity of the Ar+ ion and the He atom. The constant C was adjusted in such a way that the calculated values of the drift velocity of the Ar+ ion agree with the corresponding experimentally measured values. The cross-section was also calculated from the potential between the Ar+ ion and the He atom by the Jeffreys-Wentzel-Kramers-Brillouin (JWKB) approximation in order to check the results from the Monte Carlo simulation.
