Isotope effects at technogenic actions on solids surface

The review of the latest researches and the new experimental data obtained by the authors on changing the isotope composition in near-surface layers of solids in ion scattering processes, ion sputtering, the secondary ion emission, ion implantation, electrolysis saturation by hydrogen isotopes, thermodiffusion from external source are discussed. In all these processes the appreciable changes in natural isotopic composition of the near-surface layer have been registered. These changes take place among the secondary emitted and reflected particles also. Investigations of these effects have been made by methods of secondary ion mass spectrometry and secondary ion energy-mass spectrometry. The many-isotopic samples of molybdenum, copper implanted nickel, titanium, thin film titanium-aluminium systems and some others have been used. The general regularities in changing the isotope composition in different processes are found. The possible mechanisms of these processes are discussed
