Semiphenomenological classical non‐equilibrium collective treatment of short‐lived large energy fluctuations (SLEFs) of heavy particles (atoms, etc.) in bulk and on surfaces of solids up to ε ≧ E ≫ kT are considered. The SLEF probability and rate constants are calculated. In the Arrhenius approximation the calculated pre‐exponential factors are exponential functions of E , effective coordination numbers χ eff , Debye temperatures θ, etc. The new interpretation of diffusion and desorption experimental data narrowing the discrepancies between the latter and theoretical predictions is suggested.
