“…The same refers to the elements which are lighter than carbon and have a nucleus charge Z < 6, i.e. such elements as 1 D, 2 He, 3 Li, 4 Be and 5 B, since they cannot be registered by an x-ray microprobe spectrometer.…”

“…The element compositions of the synthesized particles and objects as well as the surface structure of the deuterium high-pressure chamber (DHPC) elements have been studied using samples of a number of metals and alloys as Al, V, Cu, Pd, Sn, Re, Pb, YMn2, stainless steels in the shape of cylindrical rods and wires, placed in gaseous molecular deuterium under high pressure and subjected to the action of braking γ-rays with energies of 10 MeV [1][2][3][4][5][6] and 23 MeV [7][8][9][10][11]. Analogous investigations aimed at studying the possibilities of nuclear reactions were carried out using hydrogen high pressure chambers (HHPC) in presence of palladium [12,13] and tin rods, as well as with hydrogen only without any metallic samples inside [14], under irradiation with 10 MeV braking γ-rays.…”

High-pressure chambers filled with gaseous hydrogen (HHPC), deuterium (DHPC) and helium (HeHPC) under different initial pressures from about 1 kbar up to 3 kbar were irradiated with braking γ-rays of threshold energy 10 MeV during varying periods of exposure at the electron beam currents 22-24 µА. Upon opening of these chambers, a lot of new synthesized structures with unusual element compositions very different from the initial ones were found. The described phenomena agree well with a series of studies by authors carried out under the action of γ-rays on dense gases of hydrogen, deuterium and helium in the presence of chosen metals in the reaction chamber.

A HeHPC (Helium high pressure chamber) filled up with pure gaseous helium at initial pressure about 1.1 bar was irradiated by braking γ-rays of 10 MeV threshold energy during 1.0 × 10 5 s at the electron beam current 22 ~ 24 μА. After irradiation, the residual pressure inside was equal to 430 bar. Synthesized foils of black color and other multiple objects were found inside the HeHPC mainly at the entrance window for γ-rays made from beryllium bronze as a plug of beryllium bronze HPC, at the inner surfaces of the reaction chamber made of high purity copper and at the copper collector. The element analysis, using SEM (Scanning electron microscopy) and MPRA (Microprobe roentgen analysis), allowed us to establish that the foils consist predominantly of carbon and the smaller quantities of other elements from carbon to iron. An explanation for the observed elements is suggested on the basis of helium fusion reactions under the action of γ-rays with the reactions taking place in giant stars (thermally activated). The possible mechanism after 3α reaction is nα reactions and under barrier reactions. A second experiment with initial pressure of 3.05 kbar (with pressure drop by about 65 bar -after almost the same procedure of γ-rays irradiation and with fully beryl bronze environment) suggests another possible nuclear reactions -He(Be, p)C, He(C, γ)O, and so on. The developed approach agrees well with a series of studies carried out by the authors where dense hydrogen and deuterium gases are acted on by γ-rays in the presence or absence of metals in the reaction chambers.
