The paper reviews results obtained in the course of low energy nuclear reactions experimental study using the HELIS facility (LPI). The analysis of DD-reaction yields in deuterated crystalline structures at deuteron energies of 10-25 keV has shown a significant amplification effect. It was found that the exposure of deuterated targets both to 10-25 keV H+ and Ne+ ion beams and 20-30 keV X-ray radiation beams results in stimulation of DD-reaction yield. For CVD diamond and PdDx targets, it was shown that the magnitude of the neutron yield is affected by the orientation of the sample with respect to the deuteron beam. The possible explanation of the said effect may be attributed to the channeling of deuterium ions and neutron (DD reaction products) in textured targets. It was found that the heat release is much higher when D+ ion beams act upon the TiDx target than in case with H+ and Ne+ beams. The heat release depends upon the deuterium concentration in the target and the deuteron beam current density. "Additional peaks"were observed in the X-ray fluorescence spectra, but those are not related to any element and are seemingly associated with diffraction processes in deuterated palladium and CVD diamond.
