Journal ArticleDOI
Ionization and Multifragmentation of C 60 by High-Energy, Highly Charged Xe Ions
T. LeBrun,H. G. Berry,Song Cheng,R. W. Dunford,Henning Esbensen,Donald S. Gemmell,Elliot P. Kanter,Wolfgang Bauer +7 more
TL;DR: A theoretical model is presented indicating that the total interaction cross section contains roughly equal contributions from (a) excitation of the giant plasmon resonance, and (b) large-energy-transfer processes that lead to multiple fragmentation of the molecule.
Journal ArticleDOI
Nondipolar asymmetries of photoelectron angular distributions.
Bertold Krässig,M. Jung,Donald S. Gemmell,Elliot P. Kanter,T. LeBrun,Stephen H. Southworth,Linda Young +6 more
TL;DR: The measured asymmetries are in excellent agreement with theoretical calculations, which include interference between the electric-dipole and electric-quadrupole photoionization amplitudes.
Journal ArticleDOI
Experimental determination of nondipolar angular distribution parameters for photoionization in the Ar K and Kr L shells.
M. Jung,Bertold Krässig,Donald S. Gemmell,Elliot P. Kanter,T. LeBrun,Stephen H. Southworth,Linda Young +6 more
TL;DR: The measured asymmetry parameters are in good agreement with recent predictions from nonrelativistic calculations which include the interference between electric-dipole and electric-quadrupole transition amplitudes in the photoabsorption process.
Journal ArticleDOI
Ionization and fragmentation of C60 by highly charged, high-energy xenon ions.
Song Cheng,H. G. Berry,R. W. Dunford,H. Esbensen,Donald S. Gemmell,Elliot P. Kanter,T. LeBrun,Wolfgang Bauer +7 more
TL;DR: The results are interpreted in terms of a theoretical model that indicates that the total interaction cross section contains comparable contributions from ~a! excitation of the giant dipole plasmon resonance, and ~b! large-energy-transfer processes that lead to multiple fragmentation of the molecule.
Journal ArticleDOI
Manifestations of Nonlocal Exchange, Correlation, and Dynamic Effects in X-Ray Scattering
M. Jung,R. W. Dunford,Donald S. Gemmell,Elliot P. Kanter,Bertold Krässig,T. LeBrun,Stephen H. Southworth,Linda Young,J. P. J. Carney,L. Lajohn,R. H. Pratt,P. M. Bergstrom +11 more
TL;DR: In this article, the authors report precise measurements of differential x-ray scattering cross sections in Ne and He from 11{endash}22thinpthinspthinkeV and develop a method for obtaining predictions of comparable accuracy (1{percent} ).
