Some recent advances in photoelectron spectroscopic technique

Abstract

The electrostatic focussing deflection type of photoelectron spectrometer may be modified in such a way as to allow routine determination of the angular distribution parameter β, and also to provide the mass spectral breakdown pattern of the positive ions produced. Two photoelectron analyzers, a hemispherical and cylindrical type, have been used in this work and their performance assessed in angular dependence of photoelectron emission and photoion mass measurements respectively.
