For those who thought the following explanation from an previous post (positronium reacting with deuterium) - for the proper understanding of the recent Mizuno experiment (aka "deuterium fission" from the MIT colloquium) was a bit over the top... a partial level of confirmation has in fact been found in the literature.
... for the record (you heard it first on vortex)... here is
a slightly revised accounting of the hypothetical QED reaction in the recent
Mizuno experiment.
D2 + Ps2 -> 2H2 which is to say that one deuterium
molecule interacts with one positronium molecule, such that the two
positrons and two neutrons (of D2) fuse to protons, resulting eventually in
2 hydrogen molecules... actually 4 protons, 4 electrons and two electron
antineutrinos. The reaction will have a modest gain, which explains the 100+
megajoules which Mizuno saw over 30 days, but which produces NO significant
gamma radiation. In short, it is a novel new form of nuclear fusion, which
looks like "deuterium fission" in the end - two hydrogen molecules in place
of every starting deuterium molecule.
Of course the simple version of atomic D + Ps is not ruled
out, other than its lower probability of requiring monatomic deuterium as
the starting point, as well as the presumed higher stability of the Ps2
species. The Ps2 is presumed to have tunneled from the Ni-62 matrix, which
is the "gateway" or wormhole to Dirac's sea. See:

"The coldest nucleus in nature as a gateway"
OK. Here is a paper by Khankhasayev and Scarlett presenting an analysis of
the positron capture reaction by a neutron. This is the critical reaction
for the above scenario.

... and which is of particular interest, outside of the Mizuno possibility,
because it is another form of a beta reaction, and also because it is the
time inverse of the known and proved reaction of the capture of a neutrino
by a proton, which converts it to neutron. They do not say much as to the
probability, but at least it appears feasible.
In short - this Mizuno discovery could involved a novel new form of nuclear
fusion, which looks like "deuterium fission" in the end - two hydrogen
molecules in place of every starting deuterium molecule, and it may not be
as far out on the fringe as it seemed to be (yesterday).
Which is not to say that it has been vetted thoroughly, but only that the
basic operating premise seems valid, whereas before this was considered -
there was almost no other possibility of explaining the Mizuno results.
