A Search for Neutron Emission from Cold Nuclear Fusion in a Titanium-Deuterium System

Experiments on cold nuclear fusion are performed on titanium deutende (TiD₂) crystal warmed from liquid nitrogen temperature to room temperature. Fusion with an estimated thermal energy output much smaller than the expected level (10¹² to 10¹³ fusion/s·g⁻¹) is confirmed by neutron burst emission, but without excess heat production. By analyzing the temperature dependence of the neutron emission in the titanium-deuterium system, it is concluded that so-called cold nuclear fusion may actually be hot-spot fusion caused by a localized high voltage generated, along with fracture formation, in the TiD₂ by lattice strain.
