Gamma-Ray Detection And Surface Analysis On A Palladium Electrode In A Dc Glow-Like Discharge Experiment

We performed glow-like discharge experiments using deuterated palladium cathode in deuterium atmosphere to investigate the possibility of inducing low-energy nuclear reaction. Anomalous gamma ray emissions in the 80-230keV region were sometimes observed. It was assumed that a nuclear reaction took place during the experiment, producing short-lived radioisotopes, and these radioisotopes emitted the gamma rays in their decay processes. Elements and their isotopic abundance on the palladium cathodes were investigated by time-of-flight secondary ion mass spectrometry to find evidence of a nuclear reaction.
