Spin Polarized Secondary Electrons: Theory

January 1, 1986

Author(s)

David R. Penn, S Apell, S Girvin

We show that the spin polarization of the secondary electrons, P(E), yields useful information about the electron-electron interaction. The ration of majority...

Polarized Electron Probes of Magnetic Surfaces

January 1, 1986

Author(s)

Robert Celotta, Daniel T. Pierce

The magnetic properties of surfaces are now being explored with electron spectroscopies that use electron spin polarization techniques. The increased activity...

Spin Polarized Inverse Photoemission Studies of Surface Magnetism and Electron Structure

January 1, 1986

Author(s)

Daniel T. Pierce, A Seiler, J Pena, Robert Celotta

Spin polarized inverse photoelectron spectroscopy (SPIPES) is shown to be a powerful new technique to study surface and near-surface electronic structure and...

Low Energy Diffuse Scattering Electron Spin Polarization Analyzer

January 1, 1986

Author(s)

john unguris, Daniel T. Pierce, Robert Celotta

A new, compact (approximately fist sized), efficient electron-spin analyzer is described. It is based on low-energy (150 eV) diffuse scattering from a high-Z...

Computing Art: Can a Computer be Taught to Take a Paintings Measure?

January 1, 1986

Author(s)

Russell A. Kirsch

The Ocean Park paintings of contemporary artist Richard Diebenkorn glow with a soft, hazy light. Translucent, luminous colors wash over barely visible skeletons...

Automated Analysis of Operators on State Tables: A Technique for Intelligent Search

January 1, 1986

Author(s)

Thomas R. Kramer

When searching lists, the current situation is represented by a state table, and changes in the situation are brought about by operators. An automated technique...

Advanced Versions of Heat Pumps With Zeotropic Refrigerant Mixtures

January 1, 1986

Author(s)

Two heat pump cycles operating with halogenated hydrocarbon mixtures are considered. Each Coefficient of Performance (COP) increases up to 50% under extreme...

Effect of Short Cycling and Fan Delay on the Efficiency of a Modified Residential Heat Pump

January 1, 1986

Author(s)

W. J. Mulroy

The object of this study was to detennine if the use of a cycling controller would improve the efficiency of a residential air conditioner or heat pump. Cyclic...
