Ratio of tritiated water and hydrogen generated in mercury through anuclear reaction |
this is an abstract published in Applied radiation and isotopes by k.
manabe and s. yokoyama from Nuclear Science and Engineering
Directorate, Japan Atomic Energy Agency (JAEA), Tokai, Naka-gun,
Ibaraki 319-1195, Japan
-----------------------------
Tritium generated in a mercury target is a source of potential
exposure of personnel at high-energy accelerator facilities. Knowledge
of the chemical form of tritium is necessary to estimate the internal
doses. We studied the tritium generation upon thermal neutron
irradiation of a mercury target modified into liquid lithium amalgam
to examine the ratio of tritiated water ([3H]H2O) and tritiated
hydrogen ([3H]H2). The ratio between [3H]H2O and [3H]H2 generated in
lithium amalgam was 4:6 under these experimental conditions.
----------------------------
so it appears that neutrons have a higher affinity to hydrogen in its
free form eh?

Not "free" but H2 vs H2O.
There will be an effect due to the different molelcules, but it will
be tiny.
H2 will have a slightly different velocity spectrum to H2O. This will
not account for any such thing as a ratio of 4:6.
What is happening here isn't that H's are catching two neutrons
and becoming T's. What is happening is that Mercury nuclei are
getting smacked and splitting off T's. (Probably there are other
isotopes getting split off as well.) These come off as ionized
nuclei, two neutrons and a proton as a clump with no electrons.
They then move around till they form molecules.
What is being measured here is, what fraction of these form
H2 molecules (or rather T2 or TH molecules, I suppose)
and what fraction form water molecules.
That is, this experiment is measuring what is essentially a
chemistry process. Much as the abstract says, knowledge
of the chemical form is required.

Hey stooopid - from where does the oxygen orginate? The morons are
seeing an SOP lithium isotope effect during water quench.
Hey stooopid - the tritium comes from fissioned lithium. The mercury
is inert. Standard triitum production uses solid lithium-aluminum
intermetallic placed near nuclear reactor cores to contain tritium as
hydrides.
Hey stooopid - controlled hot fusion is ridiculous because
magnetohydrodynamic tolerences add rather than average at all scales,
e.g., tokamaks on the small end to the sun on teh large end.
