Scattering of Polarized Electrons from Optically Pumped Sodium Atoms

January 1, 1992

Michael H. Kelley, Jabez J. McClelland, Steven R. Lorentz, R E. Scholten, Robert Celotta
We have measured the spin-dependence for elastic and superelastic scattering of spin-polarized electrons from optically prepared sodium atoms at selected incident energies from 1.0 to 54.4 eV and for scattering angles ranging from 10-degrees to 140-degrees

Spin-Resolved Elastic Scattering of Electrons from Sodium Below the Inelastic Threshold

December 30, 1991
Author(s)
Steven R. Lorentz, R E. Scholten, Jabez J. McClelland, Michael H. Kelley, Robert Celotta
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 electrons

Spin-resolved Superelastic Scattering from Sodium at 10 and 40 eV

December 28, 1991
Author(s)
R E. Scholten, Steven R. Lorentz, Jabez J. McClelland, Michael H. Kelley, Robert Celotta
Spin-resolved superelastic electron scattering from sodium has been measured at total energies of 10 and 40 eV, for scattering angles between 10° and 140°. The angular momentum transfer, Lperp}, and the spin-resolved components L(Tperp} and L(S)perp} have

Laser Focusing of Atoms: A Particle Optics Approach

September 1, 1991
Author(s)
Jabez J. McClelland, M Scheinfein
The use of a TEM 01 *-mode laser beam has been proposed as a means of focusing an atomic beam to nanometer-scale spot diameters. We have analyzed the classibal trajectories of atoms through a TEM 01 *-mode laser beam using methods developed for particle

Laser Focusing of Atoms: A Particle Optics Approach

January 1, 1990
Author(s)
Jabez J. McClelland, M Scheinfein
The use of TEM* 01 ("donut") mode laser beam has been proposed as a means of focusing an atomic beam to nanometer scale spot diameters. We have analyzed the classical trajectories of atoms through a donut mode laser beam using methods developed for
