Angle Resolved Auger Surface Spectroscopy

November 1, 1976
Author(s)
John William Gadzuk
The angular distribution of electrons ejected in core-valence-valence Auger transitions of atoms chemisorbed on metal surfaces is considered theoretically. Since the valence electrons participating in the Auger transition are also involved in chemical

Coagulation of Aerosols With Broad Initial Size Distributions.

October 19, 1976
Author(s)
George W. Mulholland, Howard R. Baum, T G. Lee
The effect of coagulation on an aerosol with a broad initial size distribution was calculated analytically for large and small particle sizes for arbitrary time with the assumption of a constant coagulation collision frequency. It was found for the class

Comment on Field emission as a probe of the surface density of states

July 15, 1976
Author(s)
David R. Penn
It is shown that the primary contribution to the field-emission current comes from electrons with total momentum equal to zero in a direction parallel to the metal surface and that the field-emission current measures the density of states at a point

Ising critical exponents in real fluids: An experiment

July 5, 1976
Author(s)
R Hocken, Michael R. Moldover
We report precise optical measurements of the equations of state of Xe, SF_6, and CO2 very near their critical points (|T - T_c|/T_c 5 x 10^-5). We find that the critical exponents of these fluids in this region are close to the exponents calculated from

Core level shifts of rare-gas atoms implanted in the noble metals

July 1, 1976
Author(s)
R E. Watson, J F. Herbst, J W. Wilkins
By means of soft-x-ray photoemission Citrin and Hamann have observed core level shifts of Ne, Ar, Kr, and Xe atoms implanted in the noble metals and have constructed a theoretical model with which to interpret the results. We describe calculations

Electron mean free paths for free-electron-like materials

June 15, 1976
Author(s)
David R. Penn
Mean free paths for electrons in bulk jellium are calculated for electrons with energies from a few hundred to a few thousand eV and for values of r s for 1.5 to 5 where r s is the average distance between valence electrons measured in units of the Bohr
