Perhaps protons are the mechanism. Wouldn't energetic protons tend to be "focused" by repulsion of the palladium nuclei along interstitial lines in the lattice, and thus very likely to interact with the deuterons occupying the interstices? It seems the circumstance most fruitful for the occurence of fusion would be a pair of protons moving in the same direction along adjacent interstitial lines at nearly the same time. This would result in many deuterons along the path of the protons being deflected toward each other. Someone mentioned "spin alignment" as a possible reason for the D + D -> T + p reaction being favored over D + D -> He3 + N. Would opposite spins favor the former? (Opposite spins would seem to result from this scenario.)

I like this model. Actually, why not thinking of large distortions of the latice (superphonons!) produced by each reaction, propagating away and inducing new reactions? >One may ask how the chain reaction gets started.

There would be about .1 muons/sec cosmic rays originated muons passing through a cell of the size of the ones reported. >This model offers a new explanation for the long induction time needed >for fusion to start -- the Pd rod must "go critical". It also add some worries. If true, it wont be difficult to get suitable conditions for an explosion. Can you see the impact of easy to carry and home made solid state H-bombs? > Paul F.
