A high-pressure chamber filled with natural xenon (XeHPC) under initial pressure 270 bar was irradiated during 43 hours by braking γ-rays with a maximum energy of 10 MeV at the MT-25 electron accelerator at an average beam intensity of 20-22 μА. After about 14 hours of irradiation, the pressure in the ХеНРС dropped to 185 bar and did not change till the end of the irradiation cycle. Upon completion of exposure, part of the gas from XeHPC was bypassed into a separate reservoir to measure the xenon composition by mass-analyzer QMA-200. After the opening of the ХеНРС, an inner assembly without xenon was fixed at the Ge-detector for measurement of γ-spectra of radionuclides produced in the XeHPC and the background during 15 hours. A visual inspection of the inner assembly indicated that the surfaces of its elements were covered with a siskin green layer. Using SEM (scanning electron microscopy) studies and MPRA (microprobe roentgen analysis) [1], the element compositions of the synthesized micro-objects and micro-particles were determined. In order to explain the observed anomalies in the formation of new elements in the micro-particles and micro-objects, nuclear fission and synthesis reactions should be used.
