Surface Enhanced Photoadsorption and Photoyield in Small Spheres

October 12, 1981
Author(s)
David R. Penn, R W. Rendell
Calculations of the photoabsorption and photyield of small metal spheres are reported for photon energies below the plasmon energy. It is found that the excitation of electron-hole paris due to the presence of the surface results in (1) enhancements in the

Absorbed Current Electron Spin Polarization Detector

October 1, 1981
Author(s)
Daniel T. Pierce, S Girvin, john unguris, Robert Celotta
The principle of spin analysis by means of measurement of the spin dependent absorption of a polarized electron beam is presented. The spin dependent signal is enhanced relative to the spin averaged signal at an energy near which the secondary yield is

Sensory Interactive Robots

September 1, 1981
Author(s)
James S. Albus, Tony Barbera, M L. Fitzgerald, M Nashman
For robots to operate effectively in the partially unconstrained environment of manufacturing, they must be equipped with control systems that have sensory capabilities. This paper describes a control system that consists of three parallel cross coupled
