Resolved diffraction patterns from a reflection grating for atoms [PDF]

, 2002
We have studied atomic diffraction at normal incidence from an evanescent standing wave with a high resolution using velocity selective Raman transitions.

DIFFRACTIVE PHENOMENA [PDF]

Lepton-Photon 01, 2002
The most recent theoretical and experimental results in the field of diffractive scattering are reviewed. A parallel between the two current theoretical approaches to diffraction, the DIS picture in the Breit frame and the dipole picture in the target frame, is given, accompanied by a description of the models to which the data are compared.

Neutron diffraction [PDF]

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1949
The problem of neutron diffraction by crystals is treated by analogy with X-ray diffraction, consideration being given to the perfect crystal, the mosaic crystal and the powdered block. The first part of the paper deals with a comparison between X-ray and neutron diffraction and it is shown that quantitatively the two are similar, apart ...

Cholesteryl esters of saturated fatty acids: cosolubility and fractionation of binary mixtures

Journal of Lipid Research, 1987
Factors affecting the solid state miscibility of saturated chain cholesteryl esters were determined from electron diffraction and differential scanning calorimetric measurements on a homologous series which included two types of crystal packing. Electron

The image edge model

Acta Acustica, 2021
Noise from traffic, industry and neighborhood is a prominent feature in urban environments. In these environments, sound reaches receiver points through reflections and diffractions.

Chemical, isotopic and gas composition of the first-year sea ice in 2013-2015 from the data of cores taken at the BARNEO drifting stations

Лëд и снег, 2019
As a result of the work performed at the BARNEO drifting stations (2013-2015 in the polar region of the Arctic ocean), a comprehensive testing was carried out and new data were obtained on the structure of one-year sea ice, its salinity, the distribution

A Model-Based RF Hand Motion Detection System for Shadowing Scenarios

IEEE Access, 2020
With the explosive growth of mobile computing, new modes of human-computer interaction (HCI) are emerging and becoming feasible. Compared to vision-based systems that require lighting, radio frequency (RF)-based hand motion detection systems are becoming
