Spin Sensitivity of a Channel Electron Multiplier

March 1, 1988
Author(s)
R E. Scholten, Jabez J. McClelland, Michael H. Kelley, Robert Celotta
We report direct measurements of the sensitivity of a channel electron multiplier to electrons with different spin orientations. Four regions of the multiplier cone were examined using polarized electrons at 100-eV incident energy. Pulse counting and

Large Angle Superelastic Electron Scattering from Na(3P)

June 28, 1987
Author(s)
Jabez J. 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 J. 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 J. 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

Spin Dependence in Superelastic Electron Scattering from Na(3P)

January 1, 1985
Author(s)
Jabez J. McClelland, Michael H. Kelley, Robert Celotta
Measurements are presented of spin asymmetries for superelastic scattering of 10-eV spin-polarized electrons from the excited Na(3P 3/2) state created by linearly polarized laser optical pumping. Asymmetries as large as 16% are observed in scattering from
