Sn126 is in the middle of the mass range for fission products. Thermal reactors, which make up almost all current nuclear power plants, produce it at a very low yield (0.056% for U235), since slow neutrons almost always fission U235 or Pu239 into unequal halves. Fast fission in a fast reactor, or fission of some heavy minor actinides like californium, will produce it at higher yields.
A LENR experiment with Sn126 would explore the hypothesis that transmutation occurring in LENR fission is sensitive to magic number configurations. If LENR fission did occur, the experiment would show how a heavy type nucleus affects the LENR nuclear process. As LENR becomes a mainstream energy production technology, it will be tested from every possible configuration as a probe of every conceivable property of the nucleus. It is my view that LENR is not sensitive to the materials used in the formulation of the micro powder. It is based on the geometry of the nanoantenna that concentrates the electric fields that screen the nucleus as well as the driving power of the pumping currents that feed the nanoantennas. For example, tungsten has been used in the high school reactor. The key characteristic in that system is the configuration of the nanoantennas. A mix of particles of many sizes from large to very small is used in this type of reactor. This varied size of particles has been shown to amplify the LENR effect in multi-stages (stages like in a rocket) with the smallest particles showing the most EMF field enhancement. In the High school reactor, the pumping current was supplied by a high voltage spark current. I suspect that the pumping current must reach saturation levels to disable the Spaser emissions of coherent radiation. This may be the reason why the pumping current must be very high to get LENR to occur.
