ABOUT DEUTERIUM NUCLEAR REACTION RATE IN CONDENSED MATTER

(Paper presented at ICCF7) Abstract The Coulomb barrier penetrability of two approaching nuclei is computed in the frame of the W.K.B approximation. A simple model for describing the screening effect of the Coulomb nuclear barrier by the high electron concentration in condensed matter is presented. The nuclear reaction rate of the hydrogen isotope nuclei, trapped in a metallic lattice is assessed, both for the unscreened and for the screened Coulomb barrier, averaged by the Maxwell distribution. The model predicts that, in certain circumstances, for porous or grainy samples, which are subject to a negative electric potential and are heavily loaded with deuterium, very low nuclear radiation level might be detected. The results are discussed in connection with some of the very successful experiments like Miley’s metal-coated spheres.
