Spallation of Mercury: Neutron Powder Diffraction @ ORNL

[Joe D]

I'm trying to understand how the neutron powder diffraction works at Oak Ridge National Lab (ORNL) and I'm wondering what the reaction is that results in neutrons being emitted from mercury after being bombarded with ~1 to 5 GeV protons. Does anyone know where I might find this information?

p+Hg -> multiple protons and neutrons and some remaining nucleus. Pion production can happen as well. There is no fixed reaction happening.

That explains why I haven't been able to find sufficient information. Thank you very much.
