-----Original Message----- From: Horace Heffner > One solution to a large D+ (m/Q) = 2 peak would be to filter the gas to be tested through palladium, which readily adsorbs ordinary D2 and thus removes it, and then test the residual gas for He, etc. This could have the drawback that dideuterinos may be able to diffuse through palladium even without an ionizing adsorbtion process. This problem can be addressed by this procedure ...
Yes. We must assume that with a much smaller effective 'electron cloud' dideuterinos would easily diffuse - BUT this feature can probably be put to good use with a second filter that blocks deuterium molecules only - a few ceramics like magnesium oxide and some polymers come to mind as possibilities. I would add the following points to your suggestions of how this process of distinguishing the two can be done more accurately, and this will assume that the mass-spec instrument being used cannot make an accurate determination (which actually I think it can make, but for a different reason - related to magnetic susceptibility and the quadrupole interaction) There are two physical properties which are claimed to be spectacularly different between the hydrogen and the hydrino state. One is magnetic susceptibility and the other is effective spatial volume. The differences can be assumed to be huge, according to occasional comments from experts like John Farrell, department chair at Franklin and Marshall College, Mills first alma mater and the only expert from the Mills camp who seems to speak to these issues on occassion. A third likely difference is a higher boiling point but we can neglect that one for now since the first two are so substantial that nothing else will be needed, and Mills has not published the data on this. Unlike the monatomic atom, hydrogen gas is very weakly magnetic since- when bonded to form the molecule, the angular momentum of one electron is opposite in direction to that of the other. The same must be assumed to be true of dideuterinos. This is not known to me, but Farrell might know, and I doubt if Mills would tell us. However, once ionized (perhaps by the mass spec itself) there should be a big difference - which might mean many things. Including the fact that many instruments will see it. There is a table on the Wiki entry http://en.wikipedia.org/wiki/Magnetic_susceptibility ... showing the negative value of helium, which should offer a clue as to another possible technique. Since Mills is tight lipped on this subject for a variety of reasons, I wonder if it would be productive to email John Farrell for guidance. My question to Robin: have you been in touch with Farrell - and does he freely offer this kind of advice- or is he under some kind of NDA ? Jones
