A nondestructive high energy (60 keV ) x-ray diffraction method to measure the internal strain depth-profile in materials was developed using a standard 320 kV p laboratory x-ray source. Traditional x-ray strain measurements are limited to few microns of depth due to the limited…

The focus of our study is on the effect of the surface's corrugation and vibration on diffraction mediated selective adsorption (DMSA). In DMSA the normal translational energy of the atom is converted into motion parallel to the surface. For a rigid surface, this occurs at speci…
