Palladium cathodes were subjected to electrolysis for prolonged periods of time in a heavy water solution at high pressure, temperature, and current density of 0.2 A cm-2. Many elements were then found and detected on the palladium surface and confirmed using several different analytical methods. These are apparently reaction products, several elements ranging from hydrogen to lead with mass numbers up to 208. The isotopic abundance of selected elements detected after long term electrolysis was found to be drastically different to the natural isotopic abundance. This phenomenon was confirmed eight times with good reproducibility. All sources of contamination have been carefully eliminated by repeated pretreatments of the sample and the electrolysis system. From the results obtained, our conclusion is that a nuclear reaction took place during the electrolysis.
