Abstract

K and L conversion electron and X-ray photoelectron spectra for a radioactive 57Co source were measured using two electrostatic spectrometers. The structure of the source and its effect on the emitted electrons were investigated. The effect of additional evaporated gold layers on the L conversion lines was examined, too. The observed line shapes were reasonably described by means of Monte Carlo simulations. The influence of the source backing material on the K-14 line was studied.
