Bismuth-209 appears to be an excellent CF nuclear catalysis agent
when used with deuterium. It has 100% abundance. The nuclear
catalysis reaction is:
209Bi83 + 2 D* --> 213At85 --> 209Bi83 + 4He2 + 23.847 MeV [-8.560
MeV] (125 ns)
The major potential drawbacks are the presence of energetically
feasible fission reaction channels not deflated electron confined:
209Bi83 + D* --> 198Pt78 + 13C6 + 21.660 MeV [5.599 MeV]
209Bi83 + 2 D* --> 198Pt78 + 15N7 + 37.819 MeV [5.412 MeV]
bismuth has a typically low melting point, even in many alloys, and
bismuth does not sustain a viable CF lattice by itself, i.e. must be
imbedded in a useful lattice. It has a lattice constant of 4.75
angstroms, as opposed to Pd at 3.89 Å, and iron at 2.87 Å.
Interesting coincidence that the average of iron and bismuth lattice
constants is within about 2% of that of Pd. A bismuth-iron alloy
might provide a feasible CF lattice at high loading temperatures.
Bismuth has a spin of 9/2, a large value of mu = 4.5444 mu_N, and
gyromagnetic ratio of 43.75 x 10^6 rad s^-1 T^-1. It has a nuclear
magnetic resonance frequency of 6.963 MHz in a 1 T field.
Nuclear catalysis is carried out best in as large a magnetic field as
possible, using as large a B field gradient as possible. Other
considerations are documented here:
