Hi Robin The neutron “hopping” modality is indeed one way that gain could happen.
In fact you are probably referring to Hagelstein’s 1993 paper where he introduces this concept wrt palladium. I do not think he was envisioning iron as the active metal at that time. Perhaps he will be reminded of this possibility. I like it but it also demands that the 2.4 MeV gamma is attenuated via the down-conversion aspect – so there are two miracles involved. … or do you get both miracles for the price of one when you have up and down conversion together <g> ???
