[en] Following the report of Fleischmann and Pons, we (The Bavarian Bubble Bottle Team) have attempted to reproduce their claims of cold nuclear fusion, and failed. We note that our measurements would not be able to detect neutrons at the level of Jones et al. Three electrolytic cell experiments were conducted using palladium cathodes and Platinum anodes, in a 0.1 Molar solution of LiD in heavy water, without any signs of neutrons, tritium or gammas above backgrounds, and within ±0.3 Watt accuracy calorimetry, no excess heating. Excess heating at the levels of F^P would have been easily detected, if present. Intrinsic tritium, differing from each D₂O bottle tested, was however observed. The longest duration experiment ran for 21 days, and was an attempt to duplicate the large 'melting incident' of F^P. This was terminated on April 28, 1989, by throwing the vacuum-cast 22 gram, deuterium-loaded palladium cathode directly into liquid nitrogen, immediately next to a bare BF₃ counter (backed by 25 cm of moderator), in order to attempt one of the Italian ENEA neutron production variants. No neutrons above backgrounds were seen, while counting for one hour, and also none while the piece warmed to room temperature over the next hour. Post mortem analysis of the darkened, hardened Pd piece showed large crystal grains (up to 2 mmx2 mm), and continuing evolution of gas bubbles at the grain boundaries even four days after the experiment was ended. Eight weeks after loading, the catalytically active palladium piece continued to create heavy water (with exposure to oxygen in the air). (orig.)
