41. Determination of Complex Scattering Amplitudes in Low-Energy Elastic Electron-Sodium Scattering
Topic: Atomic Physics
Published: 11/1/1992
Authors: Jabez J McClelland, Steven Ray Lorentz, R E. Scholten, Michael H Kelley, Robert Celotta
Abstract: Measurements of spin-resolved elastic electron-sodium scattering have been carried out at incident energies of 4.1 and 12.1 eV, and the ratio of triplet to singlet scattering cross sections has been obtained at each energy. The ratio is used to provi ...

43. 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 ...

44. 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 ...
