Synthesis of new structures on the surface of Pd rod and HHPC elements and their chemical composition in nuclear reactions induced by bremstrahlung γ quanta with threshold energy of 10 MeV in molecular hydrogen at a pressure of 0.5 kbar

A high-pressure chamber filled with molecular hydrogen (HHPC) at a pressure of 0.5 kbar with Pd rod inside has been irradiated for 14 h with γ rays having a threshold energy of 10 MeV produced by an electron beam current of 20–21 μA. Postirradiation studies of the changes in the structure and elemental composition of Pd rod and irregularities of all internal surfaces of the HHPC elements, as well as the large synthetic structures detected, reveal the presence of light elements from carbon to calcium. Multiple small particles of lead have also been found and studied. The detected synthesized particles have complex shapes and compositions. Also, thin-walled microtubes are detected on the inner surfaces inside HHPC. Based on fission reactions of intermediate mass nuclei (descending reactions), as well as the reactions of synthesis from hydrogen and heavy nuclei (ascending reactions), an attempt to explain the anomalies that were observed is made.
