Well said, especially regarding their different nuclear magnetic properties
and spin. The two isotopes must couple with reactants, whatever the
environment, in significantly different ways.
I wonder how the magnetic susceptibility of the Pd-Ni alloy changes relative to
Pd? More unpaired electrons may make for significantly different
susceptibility and different electron interaction with D.
I wonder if a Ni-low-Pd alloy still allows the Rossi reaction to happen with
hydrogen? The Pd should strain the Ni lattice and could give some information
on just where the Rossi reaction takes place, surface or in side the lattice.

Wikipedia has a discussion of Nickel hydride with several references to
recent papers.
I'm thinking more in relative terms -- I believe it takes quite a lot of
energy to dissolve hydrogen into nickel in comparison to the relative ease with
which hydrogen dissolves into palladium (which is sometimes called a "hydrogen
sponge").
In his Arata replication, Ahern found that an alloy of mostly nickel with
less than 10% Pd takes up more hydrogen than Pd alone.
But he also found that hydrogen concentration did NOT correlate to excess
energy. However, this was with protium, not deuterium. The highest absorber was
not the most active and a low absorber was actually superior. There is a known
correlation of excess heat to deuterium concentration in Pd-D experiments,
which is completely absent in Ni-H.
This is yet another reason, one of many - why consideration of all the
evidence, giving no preference to Pd-D, points to many different routes to gain
in LENR.
In many ways, protium and deuterium as so extremely different in physical
properties (especially nuclear properties) that they should be considered to be
different elements instead of isotopes of the same element.
