Yes this is a classic paper, Peter. Another interesting conjecture wrt LENR - and to the activity in the host metal which could promote a transfer of energy (in some unknown way) when loaded with hydrogen - is to analyze the list of elements by density, but correlated to atomic weight.
There are a number of metals that are "out of place" in this listing - in
being much denser than they should be based on AMU - with the implication of
having a higher % of anomalously heavy electrons per unit of atomic wt
(AMU).
The top three are Ruthenium, Rhodium and Palladium (in that order) but they
are close to each other and all way out of place -being denser than lead
while much lower in AMU.
If this parameter (which we can call "highest proportion of relativist
electrons per AMU") was to be found accurate for LENR gain, especially with
deuterium instead of protium, then Ruthenium should be superior than
Palladium... unless another physical property figures into the equation -
which is probably the case.
That parameter would probably be "deuteron conductivity," which is superior
for Palladium... but could be possibly improved in Ruthenium by alloying...
perhaps.

Till now, as far I remember mercury has not played a role in
LENR. I have once suggested it could be used
to create active sites, by blowing hydrogen charged with
mercury vapors over a metal by forming very local
amalgam islands and these can be processed further.
Just an idea, it was never tested. I have worked with
mercury in electrolysis plants and once even as heat
transfer agent in a cyclohexanol to cyclohexanone plant.
Nasty stuff- to be avoided if possible. The evil stuff kills my pet metal
aluminum.

Poser of the Day: Why is the element mercury a dense liquid?
- there have been prior (incomplete) explanations, but it
turns out that
relativity is the culprit.
The inner electrons of Hg become much heavier than normal
electrons because
they are moving very near lightspeed - thus the higher
density of the metal
is NOT due to the nucleus but instead is due to electrons.
IOW - it is not
an issue of atomic weight, per se (mercury is denser than
lead which is to
the right of it in the periodic table).
This could have implications for LENR (to be explained in
later post).

As for one of the possible LENR connections to very heavy
electrons - check
out Fig 12 and 13
http://www.lenr-canr.org/acrobat/CirilloDtransmutat.pdf
Notice that two transmutation elements of remarkable high
density turn up.
Osmium is the densest of all elements and Rhenium is very
close. Both would
have an excess of very heavy electrons.
However, this begs the question of cause and effect.
