Abstract

The paper presents, observed by authors, some physical properties and possible crystallographic structure of the carbon rich (graphite-like) elements which were found in the high pressure chamber (HPC) fulfilled before gamma irradiation only by pure gaseous helium under pressure (1 – 3) kbar. A helium HPC filled up with pure gaseous helium at initial pressure about 1.1 kbar was irradiated by braking γ-rays of 10 MeV threshold energy during 1.0•105 s at the electron beam current (22-24) μА. After irradiation, the residual pressure inside was much lower and equal to 430 bar. Synthesized of macroscopic amount foils of black color and of 0.22 mm thickness and other multiple objects were found inside the HeHPC. The element analysis, using scanning electron microscopy (SEM) and microprobe roentgen analysis (MPRA), allowed us to establish that the foils consist predominantly of carbon and oxygen and smaller quantities of other elements (tentative weight % content: 60% C, 30% O, 3% Mg, 2% N, 0.14% Si...). Two years later some physical properties such as low density (1.20±0.20 g/cm3), high resistivity (more than E5 micro ohm m), high paramagnetic properties and medium dielectric relative constant were determined. Mechanical compressive strength to be of order of 10 MPa was noted. Temperature investigation pointed out its melting temperature to be no higher than 4000C. A new carbon-reach structure (graphite–like, with typical carbon graphite planes and with oxygen, magnesium and so on atoms between) was also postulated based on obtained diffractometer data (using Siemens D500 powder diffractometer, equipped with high-resolution Si semiconductor detector). Also the second method for element content determination (EDX), in principle, has confirmed the previous one. The theory of observed phenomenon was based on postulated so called transnucleus phenomenon which took place in dense helium irradiated by proper gamma rays. Multinuclear reaction in irradiated condensed helium seems to be a new macro, micro technology.
