How to deal with Strong Anisotropic Scattering in multigroup Monte Carlo

zjlei · 2025-06-17T13:00:09+00:00

Hi everyone! I wonder how to deal with Strong anisotropic scattering when using P1 multigroup mc neutron transport? for example when p1=1 p0=0.3 （p0 p1 ：0/1 order scattering matrix）?

Hello everyone. I have a 14 MeV neutron source and a gamma photon detector at a distance. This detector is for counting photons from inelastic reactions and capture. How do I configure a tally to output only inelastic and capture reactions separately?
