Recent ab initio theoretical studies of D-desorption in metal deuterides with a high hydrogen solubility showed that the excitation of the hydrogen subsystem results in plasmon formation leading to the generation of a strong electric field (F ~ 108 V/cm) within a lattice parameter scale of a ~ 0.3-0.4 nm. As a result, significant amount of energy, correlated with desorbing deuterons, has been released reaching values of several eV (3-4 eV), effectively producing “hot” deuterons. This deuteron acceleration process, alongside with possible large electron screening in the metal targets, could potentially enhance the yield of DD-reactions in metal deuterides. Using the CR-39 track detector technique, we showed that the electron beam stimulation of the D-desorption process of Pd/PdO:Dx and TiDx targets is caused by statistically enhanced emissions of DD-reaction products (3 MeV protons and high energy alpha particles).
