Synthesis of solid-state structures and chemical elements under irradiation by bremsstrahlung γ rays with a maximum energy of 10 MeV in condensed deuterium at a pressure of 2.2 kbar

A high-pressure chamber filled with deuterium (DHPC) under initial pressure 2.2 kbar was irradiated during 49 h by bremsstrahlung γ rays with a maximum energy of 10 MeV. After irradiation, several particles with dimensions up to 1 mm fell out of the DHPC. On the inner surfaces of the DHPC, newly formed solid micro-objects were found in the form of crystalline and amorphous microparticles, filaments, nodules and inclusions. Investigations of the elemental composition of the revealed structures, carried out with the help of X-ray microprobe analysis, showed the presence of chemical elements in them, which were absent in the reaction chamber prior to the onset of irradiation. The following chemical elements were registered: ₆C, ₇N, ₈O, ₁₁Na, ₁₂Mg, ₁₃Al, ₁₄Si, ₁₅P, ₁₆S, ₁₇Cl, ₁₉K, ₂0, ₂₁Sc, ₂₂Ti, ₂₄Cr, ₂₅Mn, ₂₆Fe, ₂₈Ni, ₃₀Zn, ₃₃As, as well as ₅₀Sn and ₈₂Pb. The experiment on the synthesis of chemical elements in deuterium confirms the results of previous experiments performed with other gases: hydrogen, helium and xenon.
