Studying electron screening effects is significant in understanding nuclear reactions involved in nucleosynthesis in the Universe. The experimental focus is on bombarding hydrogen implanted into various materials with different beams. Electron screening differs in different host materials, which is very surprising. Better understanding of the metallic targets interesting for this research is possible using different spectroscopic methods. Futher, hydrogen deserves more attention becouse of his future role in the energy system.
