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

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

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 o
