For D this may be appropriate, but it goes nowhere toward explaining H + Ni, where the reaction should be hundreds of orders weaker, due to the hugely higher Coulomb barrier, but if anything, is stronger.

Re: [Vo]:Debye of Pd
Harry, -6C is 21.2 F...below freezing.. perhaps this is why Pd research has been so sluggish? Some small population of Arrata's Pd atoms get this cold and be responsible for life after death reports? I don't know if anyone has ever thought to cool the Pd under test. ...

RE: [Vo]:Debye of Pd
I think that the Debye temp is useful, although I am not sure if it is the acoustical or optical phonons that are actually involve. I have a better "feel" for the optical phonon moderating the reaction ( as seen from the duel laser stuff) than the acoustical phonon that seem to be more involved with setting the Debye temps. But I am still "confused" exactly over such phonon modes and the ultimate interactions needed for the reactions. My mental model more easily sees the optical phonons pushing D's together then it sees acoustical phonons doing that. The heat release via phonons (effected by the Debye temp) is just part of the problem. There is also the reaction itself which seems to like the higher temps. This seems to be an exponential term that involves the temperature and the energy of vacancy formation. You need higher temps or a lower Ef. Lowering the Ef even a little seems to really help. Notice in the codep exper. that the codep on Au plating works so much better than just directly on Cu. Au in Pd really drops the Ef.

RE: [Vo]:Debye of Pd
Pd reactions possible at lower temps than Ni --yes, exactly. However the reduction of the energy of vacancy of formation is also a good thing. Cu in Ni, Au or Ag in Pd, Sn in Ti,. My understanding (as limited as it is) is that you need the phonon capability for the heat to leave the reaction areas and you need the vacancies to shuttle the H/D to and from where ever things are happening. (although I still think that there is a fair chance that the vacancies themselves may be the active site- that is vacancies with specific properties).

Re: [Vo]:Debye of Pd
Is it possible that the heat measured in these experiments was released in hot spots where the Debye temp was exceeded? That would seem like an obvious way to overcome the requirement where the main mass remains at an overall low temp.
