Sad news, Michel Buxerolle died on December 30th, aged 85. In 1989, with his colleague Jacques Kurdjian, at the French Atomic Research Center in Cadarache, he demonstrated neutron production during electrolysis of a palladium tube. This work has (for reasons you can see mentioned below) never been published before. It is published in the JCMNS Volume 21.
An Historical Experiment of Neutron Detection Near an Electrolytic Cell
Michel Buxerolle and Jacques Kurkdjian.
An electrolysis experiment performed in April 1989, with a hollow palladium cathode in heavy water showed neutrons production. The results were sufficiently reliable to exclude any experimental error. Unfortunately a similar experiment has never been attempted since then. The presence of neutrons is the signature of nuclear reactions. c 2016 ISCMNS.
At the time of the March 23 annoucement by Fleischmann and Pons  of possible nuclear fusion reactions at room temperature inside a palladium cathode, we were working at the Centre d’Etudes Nucleaires de Cadarache in France. Our laboratory was devoted to neutron dosimetry and we had access to suitable equipment for neutron measurements. For us, the easiest method to check the validity of Cold Fusion was to proceed with neutron measurement near an electrolytic experiment. We had several old palladium–silver tubes used to produce ultra pure deuterium gas for an ion accelerator. The palladium–silver tubes were 10 cm long, 2 mm outer diameter, 0.2 mm thick walls and closed at one end. We succeeded in detecting neutrons. In spite of this success, our work was quickly stopped by the head of the French Atomic Energy Commission, and no further experiments were possible.
