Abstract

Authors have clearly proven for the first time that deuterium nuclear reaction was continuously generated inside a highly deuterated solid by showing both of the excess energy and corresponding amount of helium as the reaction product generated simultaneously. Whenever there is a nuclear fusion reaction inside a metal, helium generated is unable to escape to the surroundings and is trapped in a frozen state inside that metal. The concentration of the helium within the metal will rise with increasing rate of reactions. Pd-black is under such state as the sample used and sealed within the“closed QMS”developed by the authors (closed vessel including the Getter pump and the QMS). It is completely separated from the surroundings and the internal gases are removed to create super-vacuum. The reaction product released by the“Sample-Heating”process (room temp._??_ 1500[°C]) is thus the only matter which occupies the interior of the closed vessel and its detection by the QMS is assured. When the“closed QMS”works under the above mentioned-state, it was clarified that the“ash”or the reaction product of this fusion reaction within a solid is 42He and 32He and their ratio is 42He/32He≈4. It can be concluded from the result that the main reaction product is 42He and it is created directly as an inherent feature of the solid-state nuclear fusion. Authors think that the reaction process responsible for the creation of 32He may be a different one from that creates 42He. One of which is the Rutherford reaction process and the other occurs based on the specific properties of solid, similar to the case of 42He. The existence of 31T will be required that the process is responsible for the generation of 32He as the Rutherford reaction. The proof for the existence of 31T within the“closed QMS”, however, was not obtained in this experiments.
