In their report, DEFKALION said they did no isotope analysis, yet they said there was no transmutation of Ni.
Also, they did not find Tritium, He3 or He4 among the light elements. They found lithium, beryllium and boron, though. It seems that each LENR reactor reflects a unique transmutation profile based on the degree of coulomb barrier lowering that the reactor achieves. The reaction should be called cold fission. It is near impossible for fusion to build up this light transmutation profile of these light elements one neutron or proton at a time in a stepwise repetitive fusion process. Getting past Helium 4 is not possible because it is in an island of inaccessibility. He4 being a gas will escape the nuclear active zone before a fusion process can build on it so that a step based transmutation process can get to the next higher element in the transmutation chain. In these Rossi type reactors, the coulomb barrier is lowered not all the way but just enough for some light nuclear materials to leak out of the Nickel nucleus to form light elements. Rossi reported the same thing. With many of the first 19 lightest elements found in his transmutation products; even though there were many gases in that list of elements. It is fission dear fellows; clear your minds of confusion so forget about fusion and neutron formation. Cheers: Axil
