Question MuMinusDecayAtRest neutrons 

Forum: Hadronic Processes
Date: 31 Aug, 2010
From: Tom Roberts <Tom Roberts>

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?
