Arc Measurement of Some Argon Transition Probabilities

Transition probabilities and line shape parameters for three argon lines have been measured in a wall-stablilized argon arc containing a trace of hydrogen. The H line shape measurement and the assumption of local thermodynamic equilibrium provided the determination of the argon level populations. From these three lines ten other argon line transition probabilities have been obtained by relative measurements in a pure argon arc. The results are compared with those of other investigators and sources of error are discussed.
