Anomalous Effects Involving Excess Power, Radiation, and Helium Production During D₂O Electrolysis Using Palladium Cathodes

Previous experiments showed that eight electrolysis gas samples collected during episodes of excess power production in two identical cells contained measurable amounts of ⁴He while six control samples gave no evidence for helium. However, the detection limit for helium could not be defined clearly. This study of helium diffusion into the Pyrex glass sample flasks establishes a minimum helium detection limit of 3 × 10¹³ atom/500 ml (3 ppb) for these experiments. New D₂O and H₂O control experiments involving helium measurements of electrolysis gas samples collected in metal flasks support this conclusion. This places the ⁴He production rate at 10¹¹ to 10¹² atom/s per watt of excess power, which is the correct magnitude for typical fusion reactions that yield helium as a product. Simultaneous evidence for excess power, helium production, and anomalous radiation was present in these experiments. Completely new experiments with more precise helium measurements are reported that again show simultaneous evidence for excess power, helium production, and anomalous radiation.
