The MuMinusCaptureAtRest process appears to be missing a lot of neutrons, at least compared to MARS and to a MECO simulation (details unknown):
Neutrons per mu- capture on Al ------------------------------ MARS 1.1 Geant4 0.8 (QGSP_BERT_HP) MECO 1.2
The attached file shows the KE distributions for these, and it looks like QGSP_BERT_HP is missing an important component within the nuclear physics.
How can we fix this?
