“…kT (θ ) take part in the convolution of the solution ( 16 ). Consequently, the hydrogen ready to diffuse can be regarded as the molecules located in a trap with the binding energy u 0 , while the hydrogen escaping from traps would be a transition from the u j to the u 0 energy level; this transition occurs with an energy loss equal to u j -u 0 .…”

“…The vacuum-heating method [15][16][17][18] is one of the ways for measuring hydrogen concentrations in solid samples; it is used in research as well as in the industrial monitoring. For our experiments we used an industrial AB-1 hydrogen analyzer with massspectrometric monitoring of the time dependence of hydrogen flow from a sample heated in vacuum.…”

A hypothesis of the multichannel character of hydrogen diffusion in solids has been substantiated in the paper. Based on this hypothesis, a mathematical model of hydrogen diffusion in the crystalline lattice was constructed. The model allowed determining the dissolved hydrogen binding energies using an extraction curve. The curve is measured by an industrial vacuumextraction procedure with mass-spectrometric detection of hydrogen streams. The paper presents various experimental data that supports the validity of the multichannel model and discusses the advantages and disadvantages of the proposed approach in comparison with the well-known method of thermal desorption spectra (TDS) that is recognized as the classical way of experimentally determining dissolved hydrogen binding energy in solids.
