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

December 30, 1991
Author(s)
Steven R. Lorentz, R E. Scholten, Jabez 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 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

Superelastic Scattering of Spin-polarized Electrons from Sodium

September 1, 1989
Author(s)
Jabez McClelland, Michael H. Kelley, Robert Celotta
Superelastic scattering of spin-polarized electrons from laser-excited sodium atoms has been measured at incident energies of 2.0, 17.9, and 52.3 eV over the angular range 10°-120°. Circularly polarized excitation of the sodium atoms was used to produce

Exchange Asymmetry in Elastic Scattering of Electrons by Sodium Atoms

April 1, 1988
Author(s)
D H. Oza
Calculations of the exchange asymmetry in elastic scattering of electrons by sodium atoms are reported at incident electron energies of 10 and 54.4 eV. The close-coupling calculations are performed with the four lowest target states of the sodium atom. At

Large Angle Superelastic Electron Scattering from Na(3P)

June 28, 1987
Author(s)
Jabez McClelland, Michael H. Kelley, Robert Celotta
Measurements of superelastic scattering of 2eV electrons from oriented Na(3P) atoms have been carried out over the angular range 10 to 120°. Results are presented in terms of L perp}, the angular momentum transferred perpendicular to the scattering plane

Spin Dependent Superelastic Scattering from Pure Angular Momentum States of Na(3P)

March 31, 1986
Author(s)
Jabez McClelland, Michael H. Kelley, Robert Celotta
Spin asymmetries are presented for superelastic scattering of spin-polarized electrons from spin-polarized M L=+1 and M L=-1 states of the Na 3P 3/2 atom. The incident-energy dependence at a scattering angle of 30° is shown for energies of 1.26 to 11.76 eV

Detailed Look at Aspects of Optical Pumping in Sodium

January 1, 1985
Author(s)
Jabez McClelland, Michael H. Kelley
Calculations and measurements are presented of the increase in F-bar=1 ground-state population as a function of incident laser intensity in optically pumped sodium. The calculations involve numerical integration of a multilevel version of the optical Bloch
