Previously in this thread and another related thread related to hydrogen isomers being “dark matter” and the emerging possibility that the Rossi reactor is a DDL/ Dark-Matter device…
.. this [3.5 keV] seems to be near a Rydberg emission line, and possibly already associated with deep level orbital redundancy. To wit: There are 137 steps in the progression of ground state hydrogen to DDL according to CQM. There are other ways to compute this as well. If DDL is dark matter, or a subset of dark matter, then perhaps it is not completely dark in a cosmological environment, and will emit with a signature. The final photon in that range is within the same spectral range as what was seen in the numerous papers – (which are interpreted as dark matter emission) especially if they have been red-shifted. For instance 136 * 27.2eV = 3.99 keV. This would tend to add some relevance to the need to search for x-rays in this range, in a working Rossi reactor. There are ways to do this. The payoff would be twofold if this emission line is seen. We could simultaneously explain the what dark matter consists of (basically it is DDL hydrogen) and also, explain the proximate cause of LENR producing lots of heat without a gamma signature. Jones
