Hi,

From http://atom.kaeri.re.kr/cgi-bin/nuclide?nuc=Ni-62n=2 one can see that the
cross section for neutron absorption by Ni62 at thermal energies (~ 2E-8 MeV) is
about 14 barn.
Dividing this into the atomic volume of

Yes of course - that is a thermal neutron - which changes everything. There
is no thermalization mechanism in this reactor

Hello all!
I've got a question that I believe you could help me with:
I understand that the coulomb barrier is the point at which the Strong
Force will become dominant, and overcome the natural repulsion of two
nuclei as they are moved closer together. But can neutrons penetrate the
coulomb
Craig,
I don't if this helps, but most metals tend to be relatively transparent to
neutrons, due to the scattering cross-section which is caused by spin, not by
anything related to charge. The Coulomb barrier is not involved AFIK with
neutrons.
A few metals like cadmium will absorb neutrons
