Nonlinear absorption of an X-ray pulse during the formation of warm dense matter A bright, ultrashort X-ray pulse is used to transiently create and characterize warm dense copper. As the pulse intensity is increased, the opacity of copper is strongly altered. The recorded X-ray absorption spec...
摘要: The world's first kiloelectronvolt X-ray laser produces such a high flux of photons that atoms can be 'cored'. In other words, the light source can knock out both the electrons of an atom's innermost shell.关键词: Indian Ocean tsunami Numerical modelling Field measurements Inundation...
The mechanism of X-ray CT relies on X-ray attenuation in accordance with the Beer–Lambert law to generate contrast, namely [1]I/I0=e−μt where I, I0, μ, and t are the X-ray intensities after and before transmission, the linear absorption coefficient, and thickness of an object,...
Atom RSS Feed X-ray tomography, or X-ray computed tomography, is a method for generating 3-dimensional imaged volumes from 2-dimensional X-ray image slices. X-ray imaging is based on the differential absorption or scattering of an X-ray source to reveal the internal attributes of a structure...

wavelength of the X-ray source, and phase. Phases cannot directly be measured but can be determined by several methods. After identification of all parameters, an electron density map is obtained and finally reveals the atom positions within the molecule. The protein structure can be received by...

Likewise an excited atom which emits X-rays (either bremsstrahlung or purely characteristic X-rays) also emits a spectrum of low energies including near infrared radiation by Rao effect. http://www.angelfire.com/sc3/1010/michigan1998.html Ultimately this research work was published in the ...
