11. Virtual Environment for Manipulating Microscopic Particles with Optical Tweezer
Published: 6/1/2003
Authors: Yong-Gu Lee, Kevin W Lyons, Thomas W LeBrun
Abstract: In this paper, we use virtual reality techniques to define an intuitive interface to a nanoscale manipulation device. This device utilizes optical methods to focus laser light to trap and reposition nano-to-microscopic particles. The underlying physi ...

12. Micro-Mirror Array Control of Optical Tweezer Trapping Beams
Published: 8/28/2002
Authors: Nicholas G Dagalakis, Thomas W LeBrun, J Lippiatt
Abstract: The efficiency of optical tweezer manufacturing depends on the number of trapping beams available. Micro optics technology offers the opportunity to significantly increase the number of trapping beams without a significant increase of the cost or siz ...

13. X-ray Scattering and Fluorescence From Atoms and Molecules
Published: 1/1/2000
Authors: S H Southworth, L Young, E P Kanter, Thomas W LeBrun
Abstract: 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 sc ...

14. Radiationless Resonant Raman Scattering at the Ar K Edge
Published: 1/1/1999
Authors: Thomas W LeBrun, S H Southworth, G B Armen, M A MacDonald, Y Azuma
Abstract: 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 ...
