First off, there's a difference between Bohr radius and the
Covalent radius:

Dang, a differing terminology. And they have the "van der Waals
radius" too, at 120 nm. They say: "The van der Waals radius of an
atom is the radius of an imaginary hard sphere which can be used to
model the atom for many purposes. Van der Waals radii are determined
from measurements of atomic spacing between pairs of unbonded atoms
in crystals."
This seems to be the radius I should have used to describe a lone
hydrogen atom, the one that won't fit. I felt sure the "atomic
radius" (79 nm) on my periodic chart was the radius of the stand-
alone atom, and the "covalent radius" (32 nm) was the radius of the
atom in the H2 molecule, and which is certainly smaller. Now there
are more definitions to deal with. Wow, that big 120 nm van der
Waals hydrogen radius would be even tougher to fit!

Wow! Hi Terry!

Released? Is that like fired?

How could I ever forget you Terry!
Regarding your AEH, I am over 1/3 through it and agree with many
aspects. I have always believed ionization in general could be
ou. Do you think H2 is dissociated *and* ionized in electrolysis?
Not necessarily in low voltage electrolysis, but with no doubt in the
high voltage range described in the blue glow articles <http://
www.mtaonline.net/~hheffner/GlowExper.pdf> and <http://
www.mtaonline.net/~hheffner/BlueAEH.pdf>.
BTW, I can find no information on the web which tells me if it is
molecular, atomic, or ionized H that is deposited in Pd.
This is a really complex subject. The best book I've found is Topics
in Applied Physics, Vol 73, Hydrogen in Metals III, Edited by H.
Wipf, Springer-Verlag, ISBN 3-540-61639-X.
The most exciting thing is that diffusion happens primarily by
tunneling, and typical diffusion jump rates exceed 1 THz! Diffusing
hydrogen in metals is a great environment for tunneling events, like
fuson.
My data is on my office computer. It is damned hard to find the
unit cell length of Pd!! I have a NRL report which shows 4%
swelling of the Pd lattice during hydridization (made that word
up!). I'll give you those refs tomorrow.
Yes, a small percent swelling is typical and it correlates to an
increase in resistance - which is due to electrons matched with the
adsorbed hydrogen getting tied down, in my opinion. When the nuclei
can't diffuse any longer, the electrons can't move. They are "in a
box".
