51. Spin-Resolved Elastic Scattering of Electrons from Sodium Below the Inelastic Threshold
Topic: Atomic Physics
Published: 12/30/1991
Authors: Steven Ray Lorentz, R E. Scholten, Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: A very stringent test of low-energy electron-atom collision theory is made in the most favorable energy regime for the close-coupling approximation. Data are presented as exchange asymmetries in angle-resolved elastic scattering of spin-polarized ele ...

52. Spin-resolved Superelastic Scattering from Sodium at 10 and 40 eV
Topic: Atomic Physics
Published: 12/28/1991
Authors: R E. Scholten, Steven Ray Lorentz, Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: Spin-resolved superelastic electron scattering from sodium has been measured at total energies of 10 and 40 eV, for scattering angles between 10{degree} and 140{degree}. The angular momentum transfer, L{perp}, and the spin-resolved components L(T{per ...

56. Spin-polarization, Orientation, and Alignment in Electron-Atom Collisions
Topic: Atomic Physics
Published: 1/1/1990
Author: Michael H Kelley
Abstract: The use of state-selection techniques has added greatly to our fundamental understanding of electron-atom collision phenomena. In particular, measurements of atomic orientation and alignment in electron impact excitation, and measurements of spin de ...

Topic: Atomic Physics
Published: 1/1/1990
Authors: Michael H Kelley, K Becker, P Neill
Abstract: Electron spin polarization effects and electron-photon angular and polarization correlation studies in electronic and atomic collision processes were the major subjects discussed at the Fifth International Symposium on Polarization and Correlation in ...

58. Uses of Spin-Polarized Electrons in Fundamental Electron-Atom Collision Processes and the Analysis of Magnetic Microstructures
Topic: Atomic Physics
Published: 1/1/1990
Author: Michael H Kelley
Abstract: Two experimental programs are discussed which exploit the use of polarised electrons for studies of fundamental processes and physical properties. In one program, collisions between spin-polarised electrons and optically pubped sodium atoms provide ...
