Conference paper


A number of errors may occur in plasma diagnostics. Some of these errors are insidious, interact with one another, and tend to be self-perpetuating, their effects even being amplified in certain later applications. Self-absorption, lack of local thermodynamic equilibrium, systematic error of intensity measurement with respect to wavelength, incorrect absolute transition probabilities, and plasma temperature errors are among the commonest offenders. These have become inextricably intertwined with one another and frozen into the largest and most used compendium of what is probably the most crucial plasma diagnostic parameter, the absolute transition probability or f-value. We refer, in particular, to the Corliss and Bozman N.B.S. Monograph 53 of 1962, which gives some 25,000 experimental transition probabilities for 112 neutral and singly ionized species of 70 elements; also, to subsequent lists by Corliss and collaborators.
