The cross sections vs energy generated by THERMR
are put into File 3 as simple tabulations using the
MT number (or numbers) requested by the user. The
energy-angle distributions appear as normalized
distributions in File 6. For a specified grid of
incident energies, a distribution vs secondary
energy is given on a grid chosen to represent the
actual angle-integrated function to a specified
accuracy. At each secondary energy, a specified
number of discrete scattering cosines is given with
a predetermined set of probability values. This
format allows for easy sampling in a Monte Carlo code,
and it can also produce good values for Legendre
coefficients when needed.
As an example of the THERMR run, consider the following
input deck:
