Neutrons Produced by Heating Processed Metals

We found that neutrons were generated when SUS304 alloy was compressed and tensile processed and heated from 300°C to 800°C, and the energy of the neutrons was 0.7 MeV. Here, we report on the control of neutron generation. The reactor was a cylindrical chamber that made by bending of 2 mm thick SUS304 plates. It was 10 cm in diameter and 40 cm long, with the inside surface buffed with mesh 400. Both ends were closed, hydrogen was poured into the reactor at 1 atmosphere, and then evacuated. By heating the tube and changing the temperature, it was confirmed that excess heat and neutrons were emitted. The neutron energy spectrum was confirmed by distinguishing gamma rays and neutrons using a NE213 liquid scintillator. The neutron energy had a peak at 0.7 MeV, which was significantly different from the 2.45 MeV that had been thought to be nuclear fusion up until now. This reaction was highly reproducible, and the higher the temperature, the greater the reaction.
