I used to favor this a possibility, until I finally understood what
the skeptics
were saying, namely that photons have very little "kick".
I was the one who wrote what Mr. Smith was quoting. I wasn't claiming
that the Mossbauer effect was responsible for the lack of radiation,
only that there might be some "similar" effect involving group
dynamics. Some propose that fusion within a BEC would result in a
spread of the energy over the entire cluster. Perhaps something would
happen with the electrons in the cluster. Etc.
IOW this only works as
long as a photon is ejected, and the resultant kick back energy of
the emitting
nucleus remains in the thermal energy range. That means that it is
not likely to
be applicable here because no photon is emitted (since no gammas are
detected).
In short the kick back force on the nucleus has to be commensurate with the
lattice forces holding the nucleus in position.
If an alpha were to be ejected, the kick back force would be vastly
greater, and
the remaining nucleus would be ripped from the lattice. So a
Mossbauer effect is
probably out of the question.
Sure, if it were just like that. But what if there were BEC fusion of
Takahashi's TSC. It would collapse to Be-8 *with the electrons*, and
it would be locked into the structure. What would happen when the
Be-8 decays? The nucleus is excited, but I'd think it would still
have the 3 or 4 electrons from the fusing deuterium. What would they
do? The nucleus, I'm told in one place, would emit photons in a
series of transitions, not gammas. Could the nuclear excitation
energy of about 23 MeV be transferred to the lattice under those
conditions? Then at some point the nucleus itself fissions to two
alphas. I forget if the energy is 90 KeV total or each, if the
nucleus had reached the ground state before fissioning.
Basically, I don't think we really know what would happen.
