Abstract

The problem of measuring branching ratios or transition probabilities using the technique of photoelectron spectroscopy is discussed in terms of the angular distribution of the ejected photoelectrons. Equations are developed that can be used in conjunction with any type of electron-energy analyzer to correct for any discrimination in the analyzer caused by electrons of varying angular distribution. Results are presented for the branching ratios of the A2IIu and B2u+ states of CO2+ produced by 584 Å and obtained by a variety of electron-energy analyzers.
