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

Near-Threshold Measurements of the Spin Dependence of Electron-Impact Ionization

January 1, 1983
Author(s)
Michael H. Kelley, W Rogers, Robert Celotta, S Mielczarek
The spin dependence of the electron-impact ionization of Na has been measured up to 2 eV above threshold with high precision to search for the existence of characteristic oscillations which would support the Coulomb-dipole theory of threshold ionization

Polarized Electrons

January 1, 1982
Author(s)
Robert Celotta, Daniel T. Pierce, Michael H. Kelley, W Rogers
The electron-sodium system is an excellent prototype of non-relativistic electron scattering from a quasi-one-electron atomic target, and is tractable both experimentally and theoretically. Recently, this system has been studied in a series of
