The third-order asymptotic aberration coefficients of round electrostatic electron lenses are formulated, following Hawkes, in a form independent of object and
A compilation is presented of measured attenuation lengths of low-energy electrons in solids in the energy range (40 to 2000 eV) normally employed in X-ray
A useful picture of chemisorption on metal surfaces is one in which a localized molecule is formed between the adatom and its nearest neighbor substrate atoms
The use of matrices to represent electron lenses is discussed. It is shown that it is more convenient and natural to represent a lens by a matrix and that the
Accurate calculations of focal properties of the two-tube electrostatic lens are extended to cover a range of voltage ratios from 1.1 to 10000. The accuracy of
Using a fixed frequency argon ion laser, we have studied the energy spectra of electron photodetached from OH -, NH 2 -, NH -, SO 2 -, and S 2 -. We determined
Recent measurements of the L 23VV auger spectrum of Al by Powell, have shown that the observed energy distributions do not correspond to the self-convolution of
Field-emission measurements of the total-energy distribution from a clean metal surface are shown to provide information about the density of states near the
