摘要：

With the use of a simplified model of the magnesium atom, several possible approaches to the measurement of charge exchange rates between Mg and Ar in the inductively coupled plasma were developed. Two of the approaches, which used pulsed dye lasers to populate the Mg II levels that are close to resonance for charge exchange, were tested experimentally. The experiments yielded an effective rate constant for the transfer of charge from Mg+ to Ar of 1.1 x 10(8) s-1. This value is a factor of 50 lower than previously published estimates. The rate of charge transfer from Ar+ to Mg was not determined.
