Abstrakt: A detailed spectroscopic investigation has been carried out on the “quenching” of a spark discharge and the removal of self-absorption by an air blast and choice of source conditions. It was found that the spectrum excited by an overdamped discharge was made more spark-like by an air blast, and was then very similar to that produced by an oscillatory discharge. It was concluded that an air blast blows out the arc-like discharge into which a spark degenerates. Furthermore, self-absorption was found to occur largely during this arc-like portion of the discharge. The use of an oscillatory discharge rather than an overdamped discharge was more effective in removing self-absorption than an air blast.
