Hi, Could it be that Rossi uses a Cobalt60 gamma source as catalyzer? Cobalt 60 decays to Nickel60 and emits gamma rays. The gamma spectrum could be just the right spectrum and energy to excite the Nickel nucleus. Maybe it is mainly the Cobalt60 that needs screening and not the reactor? This would explain the thickness of the lead screening. Focardi has calculated the lead screening. So he must know about the gamma rays and probably knows about the catalyzer. Once he said "I dont know and dont want to know"... Now I would believe he doesnt know, but I can hardly believe he doesnt want to know ;-)
