PLUS.. 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 it 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 photons in that range are within the same spectral range as what was seen in the paper – (which they interpreted as dark matter emission). For instance 136 * 27.2eV = 3.99 keV. This would tend to add some relevance to a search for x-rays in this range, in say 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 really is (basically it is DDL hydrogen) and also explain the proximate cause of LENR producing lots of heat without a gamma signature. Still this would only explain where the gain ultimately comes in two ways 1) From electron angular momentum reduction, if you believe Mills, or 2) Proton mass reduction, if you accepted that proton mass is variable and is a function of a strong magnetic field. The magnetic field of the DDL, as felt by the proton, is possibly as high as 12.5^137, which if you try to compute it longhand, will possibly crack your frontal cortex… Jones
