Response to: H. Gentsch, DD-fusion reactions on a PdAg(D) target in a mini-reactor
The analysis of measurements as described in the report contains a number of errors, which could probably have been avoided, had the available literature been given due consideration. The assertion that the fusion rate exceeded that in a pure gas target by a factor of 100 is at odds with results published by several teams, and probably stems from inadequate analysis of the measurements. Firstly, insufficient account was taken of the stopping of high-energy ions; secondly, it is wrong to suppose that, of all the D(+), D(2)(+) and D(3)(+) ions from the ion source that hit the cathode, only atom ions contribute to fusion reactions; thirdly, the deuterium density was underestimated, it having been falsely assumed that, in the surface layer of the cathode hit by the ion, deuterium density is solely determined by diffusion of electrolytically introduced deuterium. Several effects were disregarded when the measurements were taken and analysed. Correct evaluation of these effects would most likely have eliminated the stated discrepancy between the fusion rate measured and that predicted.
