Search for neutron production during heavy water electrolysis on palladium electrodes

The results are presented from a number of experiments in search for neutrons from the heavy water electrolysis with use of different palladium cathodes. The upper limit for the yield of neutrons from a cell with a 2.34 cm3 palladium cathode, which operated continuously for seven days, is 0.2 neutron/s (0.01 neutron/s per gram of palladium). This limit is 105 times lower than the yield claimed recently by Fleischamann and Pons.
