Abstract

Energetic charged particle emissions accompanying deuterium desorption from specially prepared Pd/PdO:Dx and TiDx targets in vacuum, stimulated by electron beam (J ~ 0.6 mA/cm2, U = 30 keV) have been studied using a set of CR-39 plastic track detectors covered with various metal foil filters. It was found that the electron bombardment of those targets is caused by statistically significant emissions of DD-reaction product (3 MeV protons), as well as high energy alpha particles (11-20 MeV). At the same time the Pd/PdO:Dx and the TiDx samples show no sign of nuclear emissions during vacuum exposure without e-beam stimulation. Extrapolation of both the DD-reaction cross section and the enhancement factor (consistent with calculated screening potential Ue = 750 eV) to very low deuteron energy allowed us to satisfactorily describe the detected DD-reaction yield in Pd/PdO:Dx target, assuming "hot" deuteron (Ed ~ 3.0 eV) generation under e-beam bombardment. This result strongly supports the theoretical prediction [1,2] with regards to electron excitation of the D- subsystem in Pd- deuterides.
