摘要
We present evidence for energetic charged particles emanating from partially-deuterided titanium foils (TiDx) subjected to non-equilibrium conditions. To scrutinize emerging evidence for low-temperature nuclear reactions, we investigated particle yields employing three independent types of highly-sensitive, segmented particle detectors over a six-year period. One experiment measuring neutron emission from TiDx. foils showed a background-subtracted yield of 57 +/- 13 counts per hour. A second experiment, using a photo-multiplier tube with plastic and glass scintillators and TiDx. registered charged particle emissions at 2,171 +/- 93 counts/hour; over 400 times the background rate. Moreover, these particles were identified as protons having 2.6 MeV after exiting the TiDx foil array. In a third experiment, coincident charged particles consistent with protons and tritons were observed with high reproducibility in two energy-dispersive ion-implanted detectors located on either side of 25-micron thick Ti foils loaded with deuterium. Our overall data therefore strongly suggest low-level nuclear fusion in deuterided metals under these conditions according to the fusion reactions d + d -> n(2.45 MeV) + He-3(0.82 MeV) and d + d -> p(3.02 MeV) + t(1.01 MeV), with possibly other nuclear reactions occurring. Important advances were particle identifications, and repeatability approaching 80% for coincident charged particle emissions. Metal processing and establishing non-equilibrium conditions appear to be important keys to achieving significant nuclear-particle yields and repeatability.
