Wiki has a superficial entry for quantum probability http://en.wikipedia.org/wiki/Quantum_probability and a more complete entry for S-Matrix http://en.wikipedia.org/wiki/S-matrix
The crux of this post is to suggest that the alumina tube reactor operates via an enhanced "probability field" favoring a rare nuclear reaction, and that the key to this probability enhancement is photonic .. via SPP - surface plasmon polaritons. Specifically, the premise is that in an intense flux of IR photons, which is initiated by incandesce, the low probability of a few nuclear reactions, especially those involving Li-6, can be enhanced and at the same time excess energy which is derived can be absorbed by the photonic flux, creating a positive feedback parameter. Because the underlying reaction is gamma free, and the sole component of ash is alpha particles, the missing mechanism (for now) is the coupling of the 3 alpha emission to the photonic flux (Li6 + Li6 > 3He). >From there on, the details of how the expected bremsstrahlung can be completely downshifted require "illumination". but the missing mechanism may have been hidden in plain view, all along. This premise is easily falsifiable. More later, Jones
