We compare the results of measurements of crystal distortions made by means of two techniques: a new kinematic X-ray diffraction technique and backscattering spectrometry of channeled MeV ions. Samples were 〈111〉 single-crystal gadolinium gallium

Backscattering spectrometry is used to investigate the depth dependence of NiSi atomic mixing induced by 300 keV Xe+ ions. Nickel films with thicknesses of 40, 64, 68, and 97 nm are deposited on 〈100〉 Si substrates and irradiated at various tempe

The oxidation of thin (up to 3000 A) TiN layers was studied experimentally. It was found that the TiN layers transform into TiO2 with a rutile structure during heat treatment at temperatures around 500 °C in oxidizing ambient. The growth of the oxid

A method of calculating particle trajectories in planar channels distorted by the presented. The equation of motion is solved in the harmonic oscillator potential approximation making it possible to estimate the dechannelling probability of initially

A computer simulation model is used to investigate the possibility of particle penetration through distorted atomic planes and subsequent rechanneling in the neighbouring channel. It is found that such processes significantly influence the dechanneli

We investigated the effects of thin Si 16 O 2 and Si 18 O 2 interfacial layers on Pd 2 Si formation using He + backscattering spectrometry and the 16 O(d,α) 14 N and 18 O(p, α) 15 N nuclear reactions. SiO 2 films from 10 to 50 A thick were formed o

Applications of backscattering of 1–2 MeV α-particles to the analysis of a variety of silicon structures have been investigated. This technique allows detection of medium- and heavy- mass impurities in light matrices, as well as non-destructive in

Nuclear microanalysis has been applied for the determination of in-depth concentration profiles of nitrogen in oxy-nitrided high-speed steel. The concentration profiles were deduced from measurements of the nitrogen content, determined by means of th
