Deuterium desorption from the surface of decomposing palladium deuteride was studied by monitoring the atomic component of the desorbing gas using an adsorption method. A thin gold film was applied as an adsorbent active for D adsorption, but inert to D2 adsorption. The deuterium deposit thereby collected on the Au surface was analysed by means of the thermal desorption mass spectrometry (TDMS). The atomic component of deuterium, arising by desorption from decomposing PdDy was clearly detected. The experimental results obtained for PdDy, are compared with those observed during the decomposition of PdHx.
