Low Energy Electron-Hydrogen Scattering

Low-energy electron scattering by N2O

We present elastic integral, differential, and momentum-transfer cross sections for electron collisions with N2O. We show that, with a slight modification of a method of incorporating polarization effects proposed recently by us Winstead, McKoy, and Bettega, Phys. Rev. A 72, 042721 2005 along with a flexible one-particle basis set, we can reproduce features in the experimental data that were no...

Low energy electron scattering from CH3Cl

Multiple scattering in low-energy electron holography

The theory of the low-energy electron point source (LEEPS) microscope is reformulated in matrix form to readily account for multiple scattering. An algorithm is developed for the storage of the structure matrix and an iterative method is used to solve the matrix equation for the structure factor. Examples of small and large clusters of atoms are given to compare single and multiple scattering. ...

Low-energy electron scattering from C4H9OH isomers

We present differential, integral, and momentum-transfer cross sections for elastic scattering of low-energy electrons by three butanol isomers, isobutanol, t-butanol, and 2-butanol. Our results were calculated with the Schwinger multichannel method in the static-exchange plus polarization approximation for collision energies from 1 to 50 eV. The present results are compared with previous calcu...

Low - energy elastic electron scattering by acetylene

Acetylene, C2H2, is a prototypical molecule in several respects. As a readily available gas and one of the smallest and most symmetric polyatomic molecules, it is amenable to both experimental and computational study. It is the smallest member of the important family of unsaturated hydrocarbons and is isoelectronic with N2, having in common with those molecules both a bonding πu orbital and an ...
