Oops. My bad.
Substituted the wrong values. Should never drink decaf.
Here is a corrected version, assuming there is no further mistake.
BTW – here are some numbers suggesting why there was no radiation signature
from the Pons cathode when it was producing excess heat from cold fusion.
A. Mass of palladium-105 104.905 GeV
B. Mass of deuteron 2.014 GeV
C. Mass of silver-107 106.905 GeV
Excess mass of fusion of A and B 14 MeV which is not cold compared to the
heat of the fusion of B+B
That excess energy from A+B is high yield – and should show noticeable
radiation.
There is no adequate way to explain away the MeV gamma in either case other
than a second miracle.
As for the problem (miracle) of overcoming a higher (apparent) Coulomb
repulsion in such a putative fusion reaction involving a heavy nucleus - where
the target is way more highly charged (compared to D+D) this can be explained.
As the deuteron approaches the positively charged target nucleus, the Pd-105
isotope, the D nucleus experiences a charge polarization such that the
"proton-end" faces away from the target and is shielded while the "neutron-end"
faces towards the target. This charge polarization is amplified by the nuclear
magnetic properties of the two nuclei producing magnetic polarization and
attraction. In contrast with D+D you would see nuclear magnetic repulsion
instead of attraction.
There could be spin coupling as well.
At any rate, by the standard of “conservation of miracles” there are still two
miracles required so no help from 105.

E. Mass of deuteron 2.014 MeV
F. Mass of silver-107 106.905 MeV
Excess mass of fusion of A and B 14 keV which is really cold compared to the
heat of the fusion of B+B (which would be three orders of magnitude higher)
That excess energy from A+B is indeed a low yield – and would not have
noticeable radiation but is thousands of times greater than chemical.

As a point of historical reference, a cursory search was done wrt the isotope
Pd-105 and its relevance to cold fusion, which turns up many hits including a
very old and very provocative detail (patent application) – which only now is
coming to light via the Biberian disclosure. AFAIK this information never made
it to the newsgroups back then.
The information goes all the way back to early 1990 in a German patent
application submitted by Hora, Miley and others. This filing was on the way
within a few months of the P&F announcement !
This early filing was apparently unpublished for many years and therefore is
new to many of us, “Cold fusion device for energy generation - with metal
layers forming interfaces “ DE4027784A1 from early 1990
https://patents.google.com/patent/DE4027784A1/en
One intriguing detail here is that Hora and Miley most likely already knew that
Pd-105 was or could be the active isotope in cold fusion, at least from the
text. This could have been merely a strong suspicion - based on the isotope’s
cross section for neutrons or its high spin… or on little known government
research that the editor of Fusion Technology would have access to (i.e. the
American Nuclear Society's journal Fusion Science and Technology which was the
premier journal at that time, edited by Miley)… not to mention Hora’s top level
credentials.
One implication of this change in perspective is that the main fusion reaction
of deuterium (D+D) to helium could be rare and possibly a red herring in the
big picture, since the main provable reaction from this sample is instead the
fusion of deuterium and 105Pd into silver - 107Ag. Many observers including
Brian Ahern remain highly critical of the helium “evidence” or lack thereof as
in Krivit’s controversial articles.
Now, instead of having to deal with a missing 24 MeV gamma, and/or helium at
less than natural background – with the evidence of silver turning up, there is
only the missing beta decay or a substitute secondary reaction - but actually
that is not nearly the problem as the missing gamma. Secondary reactions are
not demanded, as is the energetic missing gamma.
Bottom line: If this information on the transmutation of palladium into silver
from Biberian had been known earlier especially had it been known in 1990, it
could have changed things. This causes some suspicion that there are hidden
reasons why the German patent application was not published.

There is a most interesting paper by Biberian on page 10 which begins with this
background info:
“In 2001, Stanley Pons gave me a palladium cathode that had produced a lot of
excess heat. The electrode was 10cm long and 2mm in diameter. It was pure
palladium and was used in an ICARUS 9 calorimeter. The electrode stayed in my
drawer for years, until I found a laboratory that could do dynamic SIMS
(Secondary Ion Mass Spectroscopy). The equipment was a Cameca 4f machine that
can detect masses of elements with high sensitivity.”
The curious thing is that active areas of the cathode labeled as “hot spots”
contained silver isotopes and furthermore, the silver must have transmuted from
palladium over the course of the gainful runs since the cathode was pure
palladium before “lots of excess heat” was seen.
Most of the transmuted silver was the isotope 107 by a very large margin. The
ratio between Ag-107/Ag-109 was close to 10, whereas in natural silver this
ratio is 1.06.
This could mean with fairly high certainty that the single isotope of
palladium, 105Pd (which is over 22 percent of natural palladium) absorbed or
fused with deuterons to become 107Ag but without subsequent beta decay.
Therefore if we assume for the moment that 105Pd is the active isotope of cold
fusion (there are other possible conclusions but let’s start with this one)
then several things stand out.
First, this is a high spin isotope. Second it has a nuclear magnetic moment. In
fact, this isotope is the ONLY palladium isotope to have a nuclear magnetic
moment and the only high spin isotope and the Larmor frequency seems to be
similar to D. Thus the excess heat and the fusion could have been a product of
spin coupling without subsequent beta decay (so no x-ray signature or residual
radioactivity would be seen).
This is interesting information which - had it come out in 2001 could have made
a difference in the way the field matured.
