Apparently the posting you cite was garbled, because you are obviously right.
However, I would like to point out that the most mystifying thing about the
Fleischmann-Pons experiment -- and many things about it are mystifying -- is
that *none* of the nuclear physics makes sense. I say this not implying that
F&P don't know what they are talking about, but rather that many things about
the experiment -- notably the enormous dearth of neutrons observed relative to
the energy allegedly released -- fly in the face of what we *think* we know
about (d,d) reactions. Until we have a better idea of just what is happening
in this experiment, I would take any and all postings dealing with reaction
mechanisms with a large grain of salt.

This one is a lot easier. The lithium was added (as deuterated lithium
hydroxide, 0.1 molar solution) before the start of the experiment, probably
to make sure that the solution was a nice, highly-conductive electrolyte.
(Distilled water, remember, isn't very good at carrying a current.) Whether
the lithium participates from a nuclear point of view -- i.e., is required
for the cell to work -- is completely unclear to us kibitzers; it would be
interesting to hear the F&P viewpoint on this.
