Theoretical and Experimental Line Profiles of Autoionizing States as Reflected in their Electroionization Curve

Abstract

An expression is deduced to predict the profiles encountered when autoionizing neutral states are detected. The validity of the new equation is shown by comparison with a structure detected in the electroionization curve of neon and attributed to the autoionizing 2s²2p⁴3s²(³P) state of neon. The new expression furthermore explains why the structure 2s2p⁶3s(¹S) of neon appeared missing in previous work.
