In-situ nuclear reaction analysis

The principles of in-situ nuclear reaction techniques and the need for them in various fields of scientific research are considered; several examples of the application of these techniques are given. It is shown that the techniques of in-situ nuclear reactions are effective in studying the diffusion of deuterium in metals at temperatures below room temperature, the diffusion of deuterium in proton-conducting oxides, the quantum diffusion of deuterium in metals at cryogenic temperatures, and the chemical composition of oxide nanopowders when they are heated in vacuum. Promising applications of nuclear reaction techniques in situ are formulated.
