This is the final report of a one-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Single crystal palladium samples were both grown at Los Alamos and purchased from a commercial source. These samples were aligned using X-ray diffraction and cut along appropriate crystal planes. After cutting, the samples were mechanically polished and then electro-etched to remove surface damage produced by the cutting and polishing. Ion beam channeling measurements and resonant ultrasound spectroscopy (RUS) measurements were completed on palladium and palladium deuteride samples. The ion beam channeling measurements on palladium samples confirmed the crystal structure and orientation of the samples and the measurements on palladium deuteride samples confirmed the octahedral location of the deuterium atoms in the palladium lattice. RUS measurements of the elastic constants of palladium and palladium deuteride samples were compared to previous measurements. Finally, RUS measurements were also completed on a palladium tritide sample at room temperature
