Neutron multiplicity

From Tim:

Some events can apparently have a baryon-number violating set of n and p in the final state, but further examination suggest these are interactions with higher A materials that are part of the detector (iron, nickel, etc.). Most high n and high p final states feature very soft n or p (<~ 1 MeV KE). Their observability and impact is an open question. Argoneut measurements of p multiplicity did not agree with GENIE (data<model).
