Hi! Please excuse errors. English is not my native language.
If we want to make better LENR and find a start for a theory so may it bee good to leave out the nuclear physics for a moment. If cracks is the site for NAE it would be good to see watt have been done about micro cracks in metals. It must be lots of studies and theory in that topic. As I understand it small cracks is probably the NAE site but large cracks is deloading the hydrogen from the metal. The hydrogen loading makes the metal expands and create cracks. Then there becomes to much large cracks the hydrogen goes out from the metal and the reaction stops. A metal how is loading hydrogen is not in equilibrium. There are rather active processes than stationary states that is important for LENR. Its may be of interest both the size /morphology of the cracks and the processes associated with the birth and development of the cracks. Cracks may be produced in a branching pattern. A fractal crack system may have many cracks in different scales. At the birth of cracks there may be strong mechanical stress, electrical fields and discharges. Some of this have been in the discussion on "fracto fusion" (a hot fusion process) but it would have significance for LENR to. There have been lots of efforts to stimulate the reactions threw laser, sound, super waves or stuff like that. Some of them seems to bee successful. This have been an argument for that oscillations as phonons are involved, but this can also be a thing that makes cracks. Which processes is associated with formation and growth of cracks? And witch processes may be important for the nuclear process?
