I was thinking about the penetration dept of alphas and I am pleased that you looked into that. Perhaps it is time to do further checking into whether or not they are associated with the hot spots.
Robin, do you have time to make a quick calculation of the density of the nuclear reactions taking place within one of the craters? You could start with your 10,000 reactions and compare that to the volume and thus number of atoms of Pd to see how common the active sites are as compared to the general metal matrix. We might be able to take this number and effectively see how much energy would be available per atom for a trigger if spread evenly, although you may have already performed this calculation with the melting figure. I am attempting to see if the trigger would be too weak unless it comes in a small package which would tend to support the alpha or proton type of particle. The cone shape does strongly suggest that a particle type of ignition is occurring which propagates along the main momentum direction. I find it interesting that there also appears to be a coordination among the trigger and the responding sites so that the effect proceeds in a well defined direction again somewhat like a laser.

The main thing that concerns me is that we should be able to see the fast moving energetic particles outside the material. Most experiments are done inside solid containers. Alpha particles, have a range in solids of approx. 10 microns, protons somewhat more than alphas but still not much. 10 microns is a fraction of the thickness of a human hair. Nothing will make it out of a container. In experiments that worked where CR-39 was used as the detector inside the cell, fast particles have been detected. Even beta particles wouldn't make it out of a container. However they would create some bremsstrahlung which should be detected. In early experiments, some experimenters checked for "glow in the dark". None was found, though few early experiments actually worked. Perhaps now that more are successful, it's time to check again.
