We report the discovery of the new phenomenon of energetic alpha emission (up to 16.0 MeV), and proton emission (∼1.7 MeV), from a metal surface possessing a large affinity for hydrogen and loaded/excited by electrolysis, glow discharge or powerful laser. Various experiments on charged particle emission show a remarkable feature: all exhibit a similar yield per unit input energy of energetic alphas [one alpha particle per 10-15 eV input energy/Pd(Ti) target atom], independent of the excitation power of delivering method (electrolysis, glow discharge or laser irradiation). The results suggest that the mechanism of energy transfer resulting in energetic particle emission in metal targets loaded with hydrogen is similar, despite the seemingly dissimilar excitation techniques.

“…Note that energetic particles (including alpha particles) are observed at low levels in experiments with PdD (Lipson et al 2000), (Mosier-Boss et al 2007). However, these emissions have not been correlated with excess power, and the amount of energy associated with these particles is lower than the energy production observed in other experiments by more than ten orders of magnitude.…”

In recent Fleischmann-Pons experiments carried out by different groups, a thermal signal is seen indicative of excess energy production of a magnitude much greater than can be accounted for by chemistry. Correlated with the excess heat appears to be 4 He, with the associated energy near 24 MeV per helium atom. In nuclear reactions, the energy produced is expressed through the kinetic energy of the products; hence it would be natural to assume that some of the reaction energy ends up as kinetic energy of the 4 He nucleus. Depending on the energy that the helium nucleus is born with, it will result in radiation (such as neutrons or x-rays) that can be seen outside of the cell. We have computed estimates of the expected neutron and x-ray emission as a function of helium energy, and compared the results with upper limits taken from experiments.Experimental results with upper limits of neutron emission between 0.008 to 0.8 n/J are found to correspond to upper limits in alpha energy between 6.2 keV and 20.2 keV.
