Energy Absorption by N 2 O in the 4 to 14 eV Region

November 15, 1975
Author(s)
R Huebner, Robert Celotta, S Mielczarek, C Kuyatt
Apparent oscillator-strength values for transitions in the 4 to 14 eV region in nitrous oxide have been derived from electron energy-loss measurements. Detailed comparison with photoabsorption measurements in the ultraviolet region indicates a weak

Observations of Polarized Electrons by Davisson and Germer

November 15, 1975
Author(s)
C Kuyatt
Early attempts to observe electron polarization in the scattering of low-energy electrons from solids are reviewed. It is found that results published by Davisson and Germer in 1929 were analyzed incorrectly, and that they had in fact observed significant

Measurement of the Surface Density of States by Field Ionization

October 1, 1975
Author(s)
David R. Penn
It is shown that recent measurements of field ion energy distributions from clean tungsten surfaces probe the density of metal states in the vicinity of the surface. We find j() = (2/kh)m| d3rm(r) z|2(-m), where j() is the ion current a , mand m are
