Paper Abstract

Intense directional X-ray emission was observed from metal targets (Pd and Ti), which served as the cathodes in a pulsed high current (100-400 mA) and low voltage (1.0 - 2.0 keV) deuterium/hydrogen glow charge. X-ray measurements showed an intense (Ix = 1013-1014 s-1-cm-2) soft X-ray emission (with a mean energy of quantum Ex = 1.2-1.5 keV) directly from the Pd or Ti cathode. The X-ray yield is strongly dependent on a deuterium diffusivity in the surface layer of the cathode. The X-ray emission can be associated with enhanced electron screening effects at metal surfaces and interfaces and a coherent oscillation of this screening layer.
