Nuclear Physics Aspects of Cold Fusion Experiments Scientific Summary after ICCF-7

The circumstance that I made the scientific summary on Nuclear Products in Cold Fusion Experiments also after ICCF-6 1 gives to me the opportunity of combining the comparison of the results from two subsequent conferences and of discussing globally the impressive achievements gained in these last three years. The major achievement at ICCF-6 was, to my opinion, the evidence of the correlation between Excess Heat, when measured, and the production of He, observed in quantities of the same order of magnitude of what expected form the hypothesis that the reaction d + d → He + (energy) is the main source of energy in Cold Fusion experiments. This conclusion was reached by several experiments. At ICCF-7, besides the confirmation of this fact, a further striking experimental result was presented, shedding light on one of the two (or three) “miracles” that were often referred to as necessary to explain the Cold Fusion Experiments. The “miracles” are:
