63. Spin-Resolved Elastic Scattering of Electrons from Sodium
Topic: Atomic Physics
Published: 4/1/1993
Authors: Steven Ray Lorentz, R E. Scholten, Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: Angle-resolved ratios of the separate triplet and singlet spin channel cross sections have been measured for elastic scattering of spin-polarized electrons from optically pumped spin-polarized sodium atoms. The triplet-to-singlet ratios axe reported ...

64. 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 ...

65. Spin-orbit and Exchange Effects in Elastic Scattering of Spin-polarized Electrons from Spin-polarized Na Atoms
Topic: Atomic Physics
Published: 5/25/1987
Authors: Jabez J McClelland, Michael H Kelley, Robert Celotta
Abstract: We report the first measurements of elastic scattering of spin-polarized electrons from spin-polarized Na atoms as a function of scattering angle. The incident energy is 54.4 eV, and the angular range is 20{degree} - 135{degree}. Data are presented ...

66. 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 ...

68. 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 ...

70. Stimulated Generation of Superluminal Light Pulses via Four-wave Mixing
Topic: Atomic Physics
Published: 4/26/2012
Authors: Ryan Thomas Glasser, Ulrich Vogl, Paul D Lett
Abstract: We report on the four-wave mixing of superluminal pulses, in which both the injected and generated pulses involved in the process propagate with negative group velocities. Generated pulses with negative group velocities of up to vg = −c/880 ar ...
