Robin, Rhetorical question ... We've been over this many times, yet a few observers continue to believe Rossi/Focardi must have got it right: that nickel transmutes to copper, despite the lack of evidence for that proposition and the nearly insurmountable evidence against.
The copper in the ash (seen by the Swedes) comes from electromigration,
since it is in the natural isotopic ratio, which makes it strong evidence
against transmutation, not for transmutation, as is Rossi's contention.
Electromigration is mundane and expected.
The natural ratio of copper is well known and comes from the multi-billion
year old supernova event which created earth, and it would be unimaginable
that modern QM or LERN reactions can recreate this primordial event
precisely at low energy, since the parameters are so extremely different.
Thus the need for another miracle, if you believe AR.
Even with a specialized detector, Bianchini did not find positrons
significantly over background. This almost guarantees the Ni->Cu explanation
is incorrect, as well as the W-L explanation being incorrect ... as well as
the DDL explanation, as well as P-e-P->D.
... unless of course, you want to add yet another miracle - "miracle" being
a new physics explanation... which is suppression of gammas. A "natural
ratio" of copper in the ash would make it three separate miracles which are
absolutely necessary for Rossi/Focardi.
The net effect of this composite physical evidence, even if incomplete,
leaves as the best viable explanation requiring only one "miracle"
("conservation of miracles" criterion) ... some version of the
Casimir/ZPE/Mills explanation, as last man standing.
IOW - there is extremely low gamma radiation and extremely low
transmutation, but lots of heat. The process of elimination should suffice
for now, when there is too little solid evidence to back three miracles,
instead of one... so to speak.

> Curiously this is precisely in the spectrum that Bianchini/Levi was
looking at, in Rossi's original demonstration (the positron spectrum). Why
were they looking there?
Because 98% of the time, the Copper isotope Cu59 decays via positron decay
with a half life of 81.5 seconds. Cu59 is what you get when you add a proton
to Ni58, which is the principle constituent of Ni.
Hence the transmutation that Rossi claimed was happening should have
produced copious positrons, which in turn would have annihilated ambient
electrons resulting in pairs of 511 keV gammas, which is what they were
looking for.
