  As explained in readme, Hadr03 is only a survey of first nuclear interaction in an infinite medium. The products of this reaction are not tracked.
  Hadr04 is dedicated to the survey of thermal neutron elastic scattering. There are no other physics components.

 For a realistic simulation, you may start with Hadr07 (or Hadr06, NeutronSource, Hadr01, Hadr02)
