MCNPX Results
According to MCNPX, there should be an effect on the neutron asymmetries from neutron scattering. In this simulation, a bottle of D2O was placed 1 meter away from a detector. The detector and the D2O were about the same size as the ones used for the experiment at the IAC. Generating neutrons uniformly inside a plastic container filled with D2O, and given an initial directionality towards the detector, MCNPX gave the following:
As the plot shows, fewer of the lower energy neutrons make it to the detector due to scattering within the D2O. I will run another simulation with more detectors placed at different azimuthal angles as time permits.
