LIMITATIONS IN THE ENERGY RESOLUTION OF SLOW ELECTRONS,

Abstract

The study delineates quantitatively the limiting factors in resolution in electron spectrometry at very low energies. It is shown that monochromatic electron beams with energy spread Delta-E/E=0.001 may be produced well below 1 eV provided the necessary and quite possible technological effort is being made. It appears that in conjunction with standard detection schemes space charge effects and their restrictions on beam intensities pose a lower energy limit for attainable monochromatic beams. However, using coincidence counting detection schemes much lower beam intensities will suffice and then physical-chemical surface effects on the electrodes and their influence on the electron trajectories will be determining this limit.
