Ja, a fraction of an eV is what I recalled, altho my recollections from
physics lectures are... very old now, my young friend. {8^D Sloshy targets
are fine, I agree, but in Pu solution makes the ions too rarified to get
very many captures in our lifetimes. Solutions are another three orders of
magnitude more rarified than a liquid metal, if my vague recollections of
typical solubility of heavy metal salts are any better than my physics
memory.
