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.
