Investigations about the effect of electrons screening potential on fusion reactivity for cold fusion of metals

This paper aims to describe the effect of electronic screening potential on the cross-sections and reactivity for fusion nuclear reactions using the light nucleus in metals (palladium and Nickel). The fundamental expression was derived and described to determine and compute cross-sections of nuclear fusion reactions with some other related parameters as nuclear fusion reactivity. Taking into account, applying thermal ignition in stars for the deuterons' reaction and its applicability in metals. As well as the high concentration of Hydrogen isotopes which make the whole elementary and duality holes in metals of structure (fcc) like Pd, Ni, and with a density approximated to 6×(23) atoma3 This increases the possibility of fusion reaction in Hydrogen or its isotopes' positions.
