This was announced by a team of researchers led by Pamela Mosier-Boss of the Space and Naval Warfare Systems Center San Diego (California), with a study presented at the annual meeting of American Chemical Society, the first visible evidence of the production of neutrons, the particles subatomic whose presence demonstrates the atomic reaction occurred.
It was 1989 when Martin Fleischmann and Stanley Pons showed that it has obtained experimentally the Cold Fusion, arousing great outcry in the scientific community. Fusion is the reaction that takes place inside of stars, their source of energy, able to reproduce in the laboratory at room temperature this process would be an amazing achievement.
Further research then disappointed initial expectations: the rare attempts (for example, those of 2000 and 2002) to reproduce the results of 1989 and have not convinced the path of nuclear reaction at low energy has not proved viable as an alternative to "clean" nuclear fission, which is based on the common operation of nuclear power.
The testing of Mosier-Boss was conducted by dipping in a solution of palladium chloride and heavy water (water with deuterium atoms instead of hydrogen) an electrode of gold or nickel, which was passed current to trigger the reaction with a process called co-deposition to detect traces of particles emitted during the reaction has been used a plastic called Cr-39. On this material, at the end of the tests small signs were observed that would be produced only by the neutrons generated by nuclear fusion of deuterium. A small sign that indicates the possibility of triggering the so-called laboratory nuclear reactions at low energy, which are the basis of atomic fusion processes at low temperatures.
