X-ray Scattering and Fluorescence From Atoms and Molecules

January 1, 2000
S H. Southworth, L Young, E P. Kanter, Thomas W. LeBrun
Fundamental understanding of x-ray interactions with atoms and molecules provides a basis for applying x-ray methods to complex materials, such as structural determinations by x-ray diffraction and extended x-ray absorption fine structure. Compton

Radiationless Resonant Raman Scattering at the Ar K Edge

January 1, 1999
Thomas W. LeBrun, S H. Southworth, G B. Armen, M A. MacDonald, Y Azuma
Partial cross sections for Ar K-LZL3(1 D2)np, n=4 and 5 spectator Auger states excited by x-ray absorption across the K-edge were measured and compared with calculations based on the theory or radiationless resonant Raman scattering. Core relaxation and

Optical trapping of selected dielectric microparticles in air

Haesung Park, Thomas W. LeBrun
We demonstrate a method to trap a selected dielectric microparticle in air using radiation pressure from a single-beam gradient optical trap. Randomly scattered dielectric microparticles adhered to a glass substrate are momentarily detached using
