Abstract
We have studied nuclear reaction during a fracture process of piezoelectric materials in D2 atmosphere. Neutrons are generated in d-d nuclear reaction through the fracture process of LiNbO3 (lithium niobate) at the D2 gas pressure of 30 kPa above: the emission rate is 108 ± 27/h with the statistical significance of 4.0 σ, although at 18 kPa or below, neutrons are not generated. We have not observed neutrons from other tested piezoelectric materials.
