CHARGED-PARTICLE EMISSIONS FROM DEUTERIDED METALS

We present evidence for energetic charged particles emanating from partiallydeuterided 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. (The neutron experiments are discussed in a separate paper in this proceedings.) 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 observedwith high reproducibility in two energy-dispersive ion-implanteddetectors located on either side of 25-micron thick Ti foils loaded with deuterium.
