Ensemble Diffraction Microscopy: An Imaging Technique That Allows High-Resolution Diffraction Imaging Using Both Totally and Partially Coherent Sources

open access: yesIEEE Photonics Journal, 2023
Coherent diffraction microscopy (CDM) is a potential approach to image micromaterials at atomic resolution without crystals. Due to the lack of high-angle scattering, the achieved resolution is limited to several nanometers. Small-angle scattering allows

Diffraction scattering of 6Li ions from atomic nuclei [PDF]

open access: yesЯдерна фізика та енергетика, 2007
Using formalism of diffraction approximation, the elastic scattering of 6 Li ions from 28Si, 40Ca, and 90Zr nuclei has been investigated at an incident energy of 35 and 53 MeV per nucleon.

Diffraction at the LHC – antishadow scattering? [PDF]

open access: yesThe European Physical Journal C, 2001
Numerical predictions for the global characteristics of proton-proton interactions are given for the LHC energy. Possibilities for the discovery of the antishadow scattering mode and its physical implications are discussed.

Structure of alumina glass

open access: yesScientific Reports, 2022
The fabrication of novel oxide glass is a challenging topic in glass science. Alumina (Al2O3) glass cannot be fabricated by a conventional melt–quenching method, since Al2O3 is not a glass former.

GLUON PROPAGATOR IN DIFFRACTIVE SCATTERING [PDF]

open access: yesInternational Journal of Modern Physics A, 2006
In this work, we perform a comparison of the use of distinct gluon propagators with the experimental data in diffractive processes, pp elastic scattering and light meson photo-production. The gluon propagators are calculated through nonperturbative methods, being justified their use in this class of events, due to the smallness of the momentum ...

Analytical Model for Optical Scattering of Infrared Laser by Nonspherical Raindrops

open access: yesInternational Journal of Optics, 2015
Analytic model was developed to investigate the interaction of infrared laser with nonspherical raindrops. The method based on Fraunhofer diffraction and geometrical optics was presented to obtain the analytic solution for single-scattering properties by
