73. Near-Threshold Measurements of the Spin Dependence of Electron-Impact Ionization
Topic: Atomic Physics
Published: 1/1/1983
Authors: Michael H Kelley, W Rogers, Robert Celotta, S Mielczarek
Abstract: 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 ioniz ...

75. Polarized Electrons
Topic: Atomic Physics
Published: 1/1/1982
Authors: Robert Celotta, Daniel Thornton Pierce, Michael H Kelley, W Rogers
Abstract: 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 sophi ...

76. Laser Photodetachment Determination of the Electron Affinities of OH, NH^d2^, NH, SO^d2^, and S^d2^
Topic: Atomic Physics
Published: 3/1/1974
Authors: Robert Celotta, R Bennett, John L. Hall
Abstract: ^d^^d^^d^ Using a fixed frequency argon ion laser, we have studied the energy spectra of electron photodetached from OH^u-^, NH^d2^^u-^, NH^u-^, SO^d2^^u-^, and S^d2^^u-^. We determined the following electron affinities: E^dA^(OH) = 1.829^u+0.010^^d ...
