This is an interesting discussion but I have one question. The reference you mentioned suggests that the process of down conversion is extraordinarily inefficient and that the probability of a gamma being down converted is virtually nil. Did I misunderstand this for some reason? Is the process much more efficient for high energy photons?

The originating frequency of the nuclear radiation is also shared between the N particles and is therefore divided approximately equally between the N particles and is therefore also divided in its calculation by 1/N. Spontaneous parametric down-conversion (SPDC) is an important process in quantum optics, used especially as a source of entangled photon pairs, and of single photons. In quantum optics, when energy is shared between two entangled particles with one particle being excited and the other standing off at a distance, that energy is not equally divided into 1/2 the energy of the original excited particle. Energy is conserved though, and the division is *very* close to equal. When entangled particles share energy from a nuclear reaction, that energy emerges from the nuclear reaction, but the photons come out slightly off axis. The actual variation in this angle is, to a small extent, a measure of the variation of the energy/wavelength of the photon stream. To say it another way: what is collected and used in experiments is extremely close to equal, but there is a dispersion of particles which are not collected which is less close to equal. Rserence: http://people.whitman.edu/~beckmk/QM/grangier/Thorn_ajp.pdf See equations 15 and 16 in the reference. The above consideration explains how the lattice does not melt after a cold fusion nuclear reaction and there is no gamma rays that emanate from a cold fusion nuclear reaction involving N entangled particles. More specifically, those entangled particles are one or more entangled copper pairs of protons configured in an entangle proton ensemble comprising N protons.
