Dispersive coherence-enhanced radiology: Experimental test and modeling
Giorgio Margaritondo, Amela Groso
Can the photon energy dependence of coherence-enhanced radiographs lead to elemental identification? Our tests pave the way to a positive response by showing that image details do change as the photon energy crosses an absorption threshold. The observed ch ...
2002Free-Electron Laser Spectroscopy of Surfaces and Interfaces
Synchrotron-radiation sources have become, since the late 1960's, one of the fundamental experimental tools for surface and interface research. Only recently, however, a related type of photon sources - the free-electron lasers (FELs) - has begun to make i ...
1995High-Resolution Laser-Induced Fluorescence Study of a Cage Molecule, 1,4-Diazabicyclo[2,2,2]Octane, DABCO
Rotationally resolved laser-induced fluorescence spectra of the caged amine DABCO (1,4-diazabicyclo[2,2,2] octane) seeded in a supersonic He beam are recorded using a high-resolution pulsed dye laser system. Both one-photon and two-photon spectra of the S1 ...
Elsevier1993Polarization Dependence of 2-Photon Transitions in Quantum-Wells
We give explicity the polarization dependence of two-photon subband-subband transitions in semiconductor quantum wells. We consider transitions from heavy-hole subbands as well as from light-hole subbands. We study the polarization dependence in the case o ...
