[en] Neutron burstlike emissions were detected during galvanostatic electrolysis of heavy water. A sintered palladium cathode of cylindrical shape was used. After 166 h of electrolysis at 200 mA/cm², two bursts of neutrons with durations of ∼200 and 100 s were observed. The cathode temperature did not show any change. 18 refs., 5 figs., 1 tab
