11. 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 ...

13. Effective three-body interactions and decoherence of coherent atom states in optical lattices
Topic: Atomic Physics
Published: 9/15/2009
Authors: Philip Johnson, Eite Tiesinga, James V Porto, Carl J Williams
Abstract: We show that virtual excitations of neutral bosons to higher vibrational states in a three dimensional optical lattice generate effective, tunable, attractive three-body interactions. These effective processes can quickly decohere coherent states hel ...

Series: J. Phys. & Chem. Ref. Data (JPCRD)
Topic: Atomic Physics
Published: 1/12/2012
Author: Edward Barry Saloman
Abstract: The energy levels and observed spectral lines of neutral and singly ionized titanium atoms have been compiled. Tables of energy levels and spectral lines are generated for each stage. Experimental g-factors and leading percentages are included when ...

19. Exchange Asymmetry in Elastic Scattering of Electrons by Sodium Atoms
Topic: Atomic Physics
Published: 4/1/1988
Author: D H Oza
Abstract: Calculations of the exchange asymmetry in elastic scattering of electrons by sodium atoms are reported at incident electron energies of 10 and 54.4 eV. The close-coupling calculations are performed with the four lowest target states of the sodium ato ...

20. Fe xvii X-ray Line Ratios for Accurate Astrophysical Plasma Diagnostics
Topic: Atomic Physics
Published: 2/20/2011
Authors: John D Gillaspy, E. H. Silver, L. Tedesco, Joseph N Tan, Joshua M Pomeroy, J M Laming, G.-X. Chen, T. Lin
Abstract: New laboratory measurements of the Ne-like Fe xvii x-ray lines in the 15-17 Angstrom range are presented, along with new theoretical predictions. These results establish consistency between independent laboratories and opens the door to trustworthy ...
