Why are the diffraction minima in π+ and π- scattering from 12C so different?The newly observed difference between π + and π elastic differential cross sections is shown to be a consequence of Coulomb distortion. Good agreement with the data is obtained at the first minimum by assuming ...
Our basic aim in the present paper is to demonstrate that functional difference equations of the second order deliver a very natural and efficient tool to study such a kind of problems (For a thorough and up-to-date overview of the scattering and diffraction in general the readers are ...
It is also known that typical interference phenomena, such as diffraction and scattering of acoustic waves, appear in an acoustic field of the real ... S Weyna - 《Archives of Acoustics》 被引量: 5发表: 2007年 Focusing and diffraction of backscattering from fluid spheres: Comparison of the ...
aThe relative intensities of the (0 2 0) and (0 4 0) diffractions reflected a difference in the X-ray scattering of the interlayers (0 2 0)和(0 4 0) diffractions的相对强度关于flected在X-射线驱散上的一个区别夹层[translate]...
The incident beam of X-rays is partly absorbed, partly scattered, and the rest is transmitted unmodified through the specimen. The scattering occurs due to interaction between the incident X-ray beam with the electrons in the material, and the diffracted X-rays interact with each other to cause...
Partial structure factors obtained from simulations were used to investigate the sensitivity of the total structure factor to the scattering length of alkali ions. The result clearly establishes that the major difference of the FSDP between lithium and sodium disilicate glasses is due to the negative ...
They differ from prismatic spectra, since in them the colors are uniformly distributed in their true order and extent according to their difference in wave-length; while in the latter the less refrangible (red) rays are crowded together, and the more refrangible (blue, violet) are dispersed...
Figure 5. Scattering patterns on wave vector domain for the proposed artificial impedance surface, for a PEC surface of the same dimension (162 mm2) and difference between the two at three representative frequencies: (a) Metasurface 10 GHz, (b) PEC 10 GHz, (c) Difference 10 ...
A test of ray theory and scattering theory based on a laboratory experiment using ultrasonic waves and numerical simulation by finite-difference method SUMMARY The structure of the Earth is represented by a wide spectrum of small- and large-scale structures. However, tomographic imaging techniques bas...
Wide-angle x-ray scattering is the same technique as the small-angle x-ray scattering differing only by the distance from the sample to the detector, which is shorter, and thus, diffraction maxima at larger angles are observed. The crystal structure and crystal form are studied by the wide-...
