Jones,
Our conversation is becoming garbled. I'll summarize.

SPAWAR proposed the triple tracks were from the three alpha producing
reaction:
n + C12 + (9 MeV minimum kinetic energy for subsequent triple
tracks seen) --> 3 He
This was logical because that is commonly seen in CR-39 when high
energy neutrons are present. SPAWAR suggests the neutrons come from:
D + T --> 4He (3.5 MeV) + n (14.1 MeV)

I think you need to read the SPAWAR articles. SPAWAR detected triple
tracks deep the CR-39. They show the photos. Such triple tracks in
CR-39 are common when high energy neutrons are present. It is a
logical conclusion on their part that their co-deposition experiment
created enough T that DT reactions were detected. This is uncommon in
the CF field, and thus assumed to be possibly unique to SPAWAR's
technique.
Neutrons have been detected in many CF experiments, just with *very*
low branching ratios, and low neutron to tritium ratios as well.
I have seen *no* evidence that thermal neutrons exist in quantities
within even orders of magnitude of enough to account for cold fusion
excess heat. If that happened then neutron activation of lattice
elements and lattice impurities would produce a massive signal that
neutron activation had occurred. Theories which predict CF is
produced by slow neutrons are therefore without experimental
foundation. There *is* evidence in CR-39 tracks of medium energy
neutrons, on the order of 1-3 MeV, via knock-on reactions with
protons in the CR-39.
I have updated my "Cold Fusion Nuclear Reactions" article to include
a discussion of this in the "TRACE TRITIUM AND TRIPLE TRACKS"
section, basically a re-work of my earlier post. See:
http://www.mtaonline.net/~hheffner/CFnuclearReactions.pdf
I include there a reference to another earlier Russian experiment
which detected high energy neutrons.
Appended below are the posts with the above quotes in context.
Best regards,

If you are implying they are quarks, then no. Quarks do not come
"unglued" even at near TeV energies...
Sure - but according to the very same authority,
What authority?
Let's see ... How about the mainstream of physics for starters ?
deuterium does not fuse at ambient temperatures ... and never,
never, never does 12C fission from a neutron capture.
The 3 alpha reaction 12C(n,n')3alpha is well known. I don't know

If you are going to postulate "new physics" then there is
absolutely no good reason to limit it to various whims of
improbability. In fact, a "temporarily free quark" imprint is
possibly *more likely* than 12C fission ... since it need not be
permanent (whereas the carbon fission is permanent and must have
secondary gammas, which are absent) -
The triple tracks are rare. They accumulate to an observable

.... especially assuming that neither has a real precedent.
