Abstract
Intense generation of neutrons in “cold” fusion was achieved where “avalanche” phenomenon of neutrons emission was frequently observed by the deuterium forcedly penetrated into a palladium cathode (φ2cm×5cm). There found a very specific phenomenon of intense charge and discharge of deuterium in the Pd cathode during the continuous electrolysis of heavy water, and this was termed “on-off effect”. While the Pd was strongly absorbing and exhausting deuterium, the thermal behavior of the Pd was examined in detail, and it was, concluded that its feature and the generation of huge innerpressure of the Pd should be a necessary condition for the achievement of “cold” fusion reaction. It was clarified that a large amount of excess heat produced during the electrolysis was not due to “unobserved nuclear fusion” proposed by Fleischmann and Pons, but due to “reaction heat” which connected with intense absorption and explosive exhaust of the deuterium into and out of the Pd.
