A modern approach to x-ray holography
We consider technical approaches to the problem of making 3-D images of large (>10 μm) life-science samples with about 10 nm resolution . We find no existing methods and discuss the possibility of using soft x-ray diffractive techniques especially holography. We propose a new form of Fourier transform x-ray holography using a reference object consisting of an array of small pinholes formed by e...
متن کاملX-ray Absorption Spectroscopy Using X–ray Fluorescence Spectrometer
Strong characteristic Kα X-ray lines are accompanied by weak lines due to the radiative Auger effect (RAE) [1, 2]. The characteristic Kα fluorescent X-rays (K-L2,3 lines) are emitted by the 2p→1s electric dipole transition after one of the 1s electron photoionization, Though the probability is less than 0.01, one of the 2p electrons is excited into an unoccupied discrete or continuum level simu...
متن کاملQuantum Electrodynamics of Internal Source X-Ray Holographies: Bremsstrahlung, Fluorescence, and Multiple Energy X-Ray Holography
Quantum electrodynamics (qed) is used to derive the differential cross sections measured in the three new experimental internal source ensemble xray holographies: bremsstrahlung (BXH), fluorescence (XFH), and multipleenergy (MEXH) x-ray holography. The polarization dependence of the BXH cross section is also obtained. For BXH, we study analytically and numerically the possible effects of the vi...

متن کاملDevelopment and Application of Laboratory X-ray Fluorescence Holography Equipment
The X-ray fluorescence holography (XFH) method has drawn the attention of many researchers as a novel experimental technique for imaging a three-dimensional local atomic structure around a certain element in a single crystal. Synchrotron radiation (SR) has been mainly used for the measurements because of extremely weak signals which are about 0.3 % of isotropic fluorescent radiation. The measur...
