For diffraction experiments with an extremely small crystal or with very long distance from X-ray source to detecting instrument, the use of an `X-ray guide tube' (XGT) is proposed on the basis of a simple consideration and experiment with a Pyrex-glass tube. X-ray intensities through an ...
X-ray diffraction experiment was carried out to study the Na_2SO_4?2OH_2O aqueous solution at 323K withθ-θtype diffractometer. The authors described the methods and processes of obtainment of solution structure function and radial distribution function (RDF) by treating scattering data using ...

In a typical X-ray diffraction experiment, thepolymer sampleis exposed to X-ray radiation which is a form of electromagnetic radiation with ashort wave length(λ≈ 0.1nm). The X-ray radiation is often produced by bombarding a metal target with fast electrons in a vacuum tube. When created ...
The ARgonne Computer Aided Diffraction Equipment (ARCADE) is an example of an effort to develop more automated methods. The system utilizes an IBM-1130 with 4K core memory and a 500K disc storage. The computer is used to (1) control the experiment, (2) collect the data, (3) make decisio...

The diffraction experiment provides the values of |Fhkl|; however, the phase information is lost, and this is known as the phase problem in crystallography. The Fourier transform marks the frontier between what is known as the reciprocal space (the space of the diffraction pattern, hkl ...
In an X-ray diffraction experiment, the electrons of a molecular crystal scatter X-rays, yielding patterns of constructive interference recorded on an X-ray detector. The resulting images contain discrete spots, known as reflections, with intensities proportional to the squared amplitudes of the ...

(3) The measuredd spacings are binned into a histogram that amounts to a sharpened powder diffraction pattern (Fig.2b). This sharpening of the powder pattern is only possible because we observe a single crystal per shot, which differs from a conventional powder diffraction experiment. Peak ...
