Targets of deuterides TiD2, ZrD2, NbD, and CrD2 with different structures used in experiments on the study of pd and dd reactions at astrophysical energies

Methods for depositing thin layers of deuterides TiD2, ZrD2, NbD, and CrD2 on stainless steel substrates are described. Magnetron sputtering of nanolayers of the above deuterides with different textures is considered. A technology for making titanium, zirconium, niobium, and chromium deuteride targets is proposed, which will definitely verify the hypothesis of the enhancement of the dd and pd reactions due to the channeling of the deuterons in the crystals of the above deuterides.
