Measurement of exoelectrons from palladium and palladium deuteride with gas proportional counter

Intensities of exoelectron emission from strained rods of pure palladium, Pd hydride and Pd deuteride were measured. The detector was an in-line type of gas proportional counter which was specially designed for the study. Emission rates for exoelectrons from strained hydride and deuteride were partly higher than those from strained Pd. However, those from a fractured Pd were much lower than those from strained Pd. Thus, the enhancement of the emission rate was related to the desorption of hydrogen or deuterium from Pd under a strain in the range of elastic deformation. There was no difference between the counting rates and the energy spectra of exoelectrons emitted from the hydride and deuteride. No trace of fracto-fusion was observed in this experiment.
