An experimental study confirms the possibility of nuclear fusion reactions initiating in metal–deuterium targets by bombarding them with ions that are not the reagents of the fusion reaction, in particular, with noble gas ions. The yields of (d,d) and (d,t) reactions were measured as functions of energy (0.4–3.2 MeV) and mass of incident ions (He+, Ne+, Ar+, Kr+ and Xe+). Irradiation by heavy ions produced a number of energetic deuterium atoms in the deuteride and deuterium + tritium metal targets. At ion energies of ∼0.1–1 MeV the d–d reaction yields are relatively high. A model of nuclear fusion reaction cross-sections in atomic collision cascades initiated by noble gas ion beam in metal–deuterium target is developed. The method for calculation tritium or deuterium recoil fluxes and the yield of d–d fusion reaction in subsequent collisions was proposed. It was shown that D(d,p)t and D(t,n)4He reactions mainly occur in energy region of the recoiled D-atom from 10 keV to 250 keV. The calculated probabilities of d–d and d–t fusion reactions were found to be in a good agreement with the experimental data.
