Title: Cold fusion in condensed matter

A model for cold fusion in condensed matter is proposed (cold fusion of deuterons in palladium). It is assumed that the palladium-deuterium system forms an alloy, i.e., it is assumed that Pd ions as well as d/sup +/ ions are embedded in an uniform background of negative charge (conduction electrons). The model is based on an interaction potential for deuterons in solid palladium which has been estimated by means of a theoretical picture well known in the physics of liquids. In particular, the following effects are possible: 1. Cold fusion in condensed matter can take place. 2. The observed energy should be larger than that given by the fusion reactions. 3. Hitherto unknown nuclear processes must not be postulated as reported by Fleischmann and Pons. 4. The deuterons are mobile. 5. The deuterons can form close-packed clusters, and in principle a fusion reaction can take place within such a cluster. 6. Not only /sup 3/He should be produced in Pd but possible /sup 4/He too. From their theoretical picture, it can be concluded that experimental results will be strongly dependent on the condition of the materials used in the experiments. This can possible explain that only a part of experimentsmore » could show up cold fusion. A well defined condition (lattice defects, different phases, impurities, etc.) of the materials is probably the most critical point in connection with the observation of cold fusion in condensed matter. The effect should also be influenced by lattice dilatations. Experiments with other materials instead of palladium (e.g. vanadium, titanium, lanthanide metals, and different alloys) should be probably more informative.« less
