Good find Jack. Indeed, together with potassium, which turned up in the spectroscopy data which Rossi included in his first patent - we may be close to stumbling upon the "secret sauce"...
BTW - did anyone try to calculate the amp-turns of the Rossi HT reactor in
that last testing?
We have a clear image of the slots and the resistance wire, which is itself
twisted, so it is probably possible to arrive at a guess-timate of the
magnetic field involved.
100% of lanthanum is high spin with NMR properties, the resonance of which
could be calculated if the field strength were known. (La139 is ~14 MHz in a
2.3488 T field).
Wasn't there a recent reference to finding an RF field in LENR?
An RF field with the HT - especially with a magnetic field... hmmm... that
could be the smoking gun, so to speak...

Another interesting study of heat produced by lanthanum
nickel absorbing hydrogen. They note the level is higher than is typical
and attribute this to chemisorption. Could they have unintentionally
produced LENR?

The heat of adsorption for hydrogen during physisorption is
somewhere between 4 to 10 kJ/mol[1] for a typical carbon sample, but for the
LaNi5 sample, the heat of adsorption is calculated to be 30.295 kJ/mol,
agreeing with published data, which has LaNi5's enthalpy ranging from about
29 to 32 kJ/mol[2]. This increase in the heat of adsorption over typical
enthalpies for the physisorption of hydrogen is the result of the LaNi5
disassociating and absorbing hydrogen. Unlike most
materials run on the ASAP 2050, such as carbons, which employ physisorption
to adsorb molecular hydrogen, the LaNi5 employs chemisorption and actually
absorbs atomic hydrogen into the metal structure.

Very interesting Jones. This paper has some intriguing
facts about lanthum and hydrogen aborption and release in lanthum.

Magnesium hydride does store more hydrogen than most metals
and alloys - by weight, since magnesium is very low density - but the Space
program in Europe and NASA use lanthanum nickel (LaNi5) for hydrogen
storage. Rossi would have access to this alloy through U-Bologna. Low weight
is not needed by the HotCat so my suspicion is that he uses a high-nickel
alloy of some kind instead of magnesium. Lanthanum has magnetic properties
that would favor its use in an active alloy.
