Abstract
The superlattice ordering transition in PdH0.64 is detected by implanted muon spectroscopy. The temperature dependence around 50K of the static μSR depolarisation rate, measured in low transverse magnetic field in a polycrystalline sample, indicates appropriate changes in the average number of nearest neighbour protons. These measurements establish the similarity of the proton-proton and muon-proton interactions within the interstitial lattice. The implanted muons reveal the onset of short range order as the transition is approached and, to the extent that vacancy sites are available, participate in the predicted structure below the critical temperature.
