" First of all, there is a crude assay based on the size of the pure sphere - and no evidence of large imbalance of Li-7 elsewhere. More importantly, 85 years of nuclear physics can present no thermal process where the bulk isotopic distribution varies more than a few percent per stage, yet the Lugano report, if it can be believed shows extremely pure Li-6 appearing in what is essentially one stage in one sample - many orders of magnitude purer than any know process can deliver. There are three possibilities - either the starting material was enriched in pure Li-6, which is most likely, or else the process of heat generation has converted the missing Li-7 into Li-6, which is endothermic, and unlikely to have happened in a process where excess heat is generated. The third possibility is that the ash was spiked with pure isotope. Neither of these possibilities can in any way support a conclusion of lithium-7 plus proton fusion, especially with the lack of the expected gamma, and no indication of helium. To say that Levi's crew did not test for helium is a complete cop-out and only indicative of further incompetence on the part of this team. With this claimed excess heat over 30 days there should have been a large amount of helium, actual overpressure: that is - if lithium fusion were taking place. A sample of gas should at least have been stored for later testing. Most likely conclusion - Rossi understood from the start that lithium-6 is the active isotope, and he provided fuel which was highly enriched, and at the same time, provided a different fuel for the testing of the "before" sample. Only Rossi handled this fuel. He had complete control, and no one complained. BTW - The cost of that much lithium-6 (about 50 milligrams) available from several suppliers, is about $10. Jones What I drew from the report was the only thing that can be concluded was that the 7Li is more commensurate to the 6Li in the ash as compared to the fuel. There was no mass assay that determined how much total Li was present in the ash compared to the fuel. We know that physically, a lot of the Li will be on the walls of the alumina tube, so we don't have any idea of the absolute depletion of Li mass in the reaction. While it is possible that the 7Li is converted to 6Li, it is only one of the possibilities. The ICP-MS analysis is a full volume analysis and showed both Li isotopes near equal in percentage in the ash. How these isotopes became nearly equal is just blind speculation at the moment without further experimental data. All of the possibilities for the ratio change from fuel to ash should be laid out and the plausibility of each examined. Bob
