None Wrong branching ratio in 241-Am Radioactive decay?

I cannot get the low energy gammas and electrons to come out with the correct branching ratios in the Am-241 decay. I am using geant4.9.0.p01. I have made the changes suggested by Luciano in Bug reports 952 and 968. I have added Np to the materials table as suggested in Message 349. The most obvious disagreements are for the 59.5 keV gamma, it should have intensity of 35.9%, but RDM is producing over 50%. Also, the 37.1 keV CE L electron is produced only at 8% instead of 30.2%. The alphas appear to be correct. The commands I use are:

/gps/particle ion

/gps/energy 0 keV

/gps/ion 95 241 0

/grdm/nucleusLimits 241 241 95 95

Any suggestions are greatly appreciated! Michelle
