Abstract
The Ar component in a molecular beam obtained in the discharge of a binary mixture of Ar and He from a nozzle source is investigated with a time-of-flight method. The excited Ar atoms formed by electron impact are recorded. It is shown that for an appropriate choice of recording-system parameters the contribution to the total signal from the mixture comes mainly from the Ar* atoms. The method described is used to study the dependence of the intensity, velocity, and enrichment factor of Ar on the Ar concentration in the starting mixture.
